International Conference Series on Recent Progress in Many-Body Theories (RPMBT)

The International Conference Series on Recent Progress in Many-Body Theories (RPMBT) is now firmly established as the premier series of international meetings in the field of many-body physics. The conferences offer an ideal opportunity to recognize important achievements and to showcase significant new results in various aspects of many-body physics. The series acts too to highlight entirely new and rapidly evolving fields which are themselves increasing both the breadth and depth of the discipline of quantum many-body theory, which underpins so much of modern physics.

The RPMBT series is governed and overseen by an International Advisory Committee. The general format and style of the conferences in the series follow an accepted and well-developed pattern, focusing on the development, refinement and important applications of the techniques of quantum many-body theory. The intention of the series has always been to cover in a broad and balanced fashion both the entire spectrum of theoretical tools developed to tackle the quantum many-body problem and their major fields of application. One of the main aims of the series is to foster the exchange of ideas and techniques among physicists working in such diverse areas of applications of many-body techniques as quantum fluids, condensed matter physics, nuclear and subnuclear physics, quantum field theory, astrophysics, atomic and molecular physics, quantum chemistry, complex systems, strongly correlated electronic systems, quantum magnetism, ultracold atoms, and quantum information theory.

Next Meeting in the RPMBT Series (23-27 September 2024)

The 22nd International Conference on Recent Progress in Many-Body-Theories (RPMBT-22) will take place during the week 23-27 September 2024, in Tsukuba, Japan. See here for the 2nd Circular.	RPMBT-22 Venue (Tsukuba, Japan)

The IAC is responsible for selecting the range of Topics that is covered by the RPMBT series. One of the primary duties of the IAC is to select the venue and the Principal Organiser(s) of the next meeting in the Series, who will in turn act as Chair(s) of the Local Organising Committee for that Conference. The IAC is also responsible for arranging the eventual publication of any Conference Proceedings. The IAC has also arranged with World Scientific Publishing Co. to publish an ongoing Series on Advances in Quantum Many-Body Theory.

RPMBT International Advisory Committee

The current composition of the International Advisory Committee is:

• Cristian D. Batista (Knoxville, Tennessee, USA)

Announcement: Open Call for Bids to Host a Future RPMBT Conference

Those wishing to host a future conference in the RPMBT Series should bear in mind that the conferences are usually held every two years, on a three-meeting rotation sequence that sees the venue cycle between Europe, North America and Elsewhere in the World. Bidders should contact the Chair and/or Secretary of the IAC in the first instance, with the aim of addressing or making further inquiries about all or most of the points on the Checklist below. For initial planning purposes the IAC suggests to think in terms of a 5-day meeting, including a half-day excursion and a conference banquet, for roughly 120 ± 10 registered participants, as has been the usual format of meetings in the Series.

Checklist of Points to Address in a Bid to Host an RPMBT Conference

1. Possible dates and venue.
2. Expected costs and budget.
3. Range of accommodation possibilities (e.g., hotels, student dormitories) and anticipated costs for attendees.
4. Any special local points of interest that would make the venue stand out or be particularly attractive to participants?
5. Details of any possible sources of financial or other support from within the university or from external agencies.
6. Level of local interest and possible involvement from faculty members within the host organizer's university or other universities or laboratories close by, naming those who might be on the Local Organizing Committee and who would be Chair.
7. Anticipated level of any registration fee to be charged.
8. Anticipated level of support to be offered to speakers (e.g., the IAC would expect all or some of: registration fee waived, local accommodation and/or subsistence covered, all or partial travel support, etc.). At the very least, registration fees for speakers should be waived, and local subsistence offered to those who need it. In the past, many organizers have also often offered (at least partial) travel support to speakers. FULL costs will also be expected to be covered for the Feenberg and Kümmel Prizewinners (if needed).
9. How many speakers? Lengths of talks? All the same length or some "keynote speakers" given more time to introduce a subject more broadly? Any parallel sessions envisaged (-- be aware that these have generally been strongly discouraged in the past)? Poster sessions (-- generally encouraged)? Any other new ideas for format of meeting?
10. Would you wish to have any "special focus" for part of the meeting, e.g., to cover any "special topics" of local or "hot-topic" interest? Would there be any local pressure to do so, to make the meeting viable?
11. Any other special features that you could offer or would like to suggest for discussion by the IAC to make your meeting or your venue distinctive? Possibilities might be the arrangement of a "Student Day (or Days)" before the meeting"; a Summer School before or after the Conference, or some special session or event during the conference hooked to a local "center of excellence" or some such thing; or some other novel feature to make the meeting distinctive and/or attractive to a wider audience. Be aware that such "special events" as part of a meeting or associated with it can also often be attractive to funding bodies.
12. Arrangements for Session for the Feenberg and Kümmel awards will need to be made.
13. Be aware that Proceedings of the meeting will be published (presently through J. Phys. Conf. Ser.) -- organizer needs to agree in advance to liaise with publisher and arrange all details, including payment of costs, to ensure prompt publication.

The Development of Quantum Many-Body Theory

Quantum many-body theory as a discipline in its own right dates largely from the 1950's, and is hence in many senses already a mature subject. Despite this apparent maturity the field remains vibrant and active, vigorous and exciting, vital and important. Indeed, the successes, importance and vitality of the field as the 20th century drew to its close, were very clearly recognized, for example, by the sharing of the 1998 Nobel Prizes in both Physics and Chemistry by the many-body theorists Robert Laughlin for his work on the fractional quantum Hall effect, Walter Kohn for his development of the density-functional theory, and John Pople for his development of computational methods in quantum chemistry. Earlier Nobel Laureates who obtained their awards for work in quantum many-body physics include: Lev Landau (1962), John Bardeen, Leon Cooper, and John Robert Schrieffer (1972), Philip Anderson, Sir Nevill Mott, and John van Vleck (1977). More recent laureates have been Alexei Abrikosov, Vitaly Ginzburg, and Tony Leggett (2003) for their pioneering contributions to the theory of superconductors and superfluids. Most recently, in 2016, David Thouless, Duncan Haldane and Michael Kosterlitz shared the prize for their theoretical discoveries of topological phase transitions and topological phases of matter.

It is impossible to date the precise origin of quantum many-body theory as a subject in its own right. Nevertheless, even if 1958 is not the actual year of its birth, that year marks a particularly significant milestone in its development. Although much important work was done earlier, even considerably earlier, that single year and the few around it saw the publication of a large number of seminal papers by such forefathers of the field as Eugene Feenberg, Richard Feynman, Murray Gell-Mann, Jeffrey Goldstone, Lev Landau, David Pines and many, many others. Possibly the most important of those others is Keith Brueckner, whose path-breaking work dates from even earlier in the 1950's.

The history (and immediate pre-history) of the series itself provides a mirror in which to view later developments in the subject, as we discuss below.

Today, quantum many-body theory stands as one of the three great pillars of modern theoretical physics, together with quantum field theory and statistical physics. While quantum many-body theory was born largely out of quantum field theory in the 1950's, the two subjects thereafter have led rather separate lives. In recent years, however, the boundaries between them have again become eroded. Indeed, many papers in recent proceedings volumes of the RPMBT series concern themselves very productively with topics on this boundary. There is little doubt that the barriers between all three fields will increasingly be surmounted in the coming years, to their mutual advantage, leading to an increasing commonality of both approach and areas of discourse.

Pre-History of the RPMBT Series

In the 1970's the applications of quantum many-body theory in nuclear physics were becoming sufficiently varied and sophisticated that a number of conferences on the subject were organized. With hindsight it is clear that these formed the impetus to the later development of the conference series on Recent Progress in Many-Body Theories (RPMBT). The most important of these early meetings, which can be regarded in many ways as having been RPMBT-0, is the 1972 conference on The Nuclear Many-Body Problem organized by F. Calogero and C. Ciofi degli Atti in Rome. Additionally, and before the official beginning of the RPMBT series, there were two very significant workshops held in 1975 and 1977 at the University of Illinois, Urbana, USA with Vijay Pandharipande as the chief organizer.

The attendees of the latter of these two meetings, the Workshop on Nuclear and Dense Matter, held during May 3-6, 1977, are shown in the photograph. It is noteworthy how many of those who either already were, or who later turned out to become, key figures in the field of quantum many-body theory, attended this meeting.	Workshop on Nuclear and Dense Matter (Urbana, IL, USA; May 3-6, 1977) Attendees
The photograph is noteworthy in several respects: Firstly, in view of the special Feenberg Award discussed below, which is named after him, it depicts Eugene Feenberg at one of the relatively few conferences he ever attended. Although we know with certainty that he had fully intended to attend the RPMBT-1 meeting, he died in 1977, a year before it was held. Secondly, it shows that this precursor Urbana meeting was attended by four future Feenberg Awardees.
A detailed list of those portrayed in the photograph can be found by clicking on the picture.

History of the RPMBT Series

In response to the several precursor meetings discussed above that accentuated the need for a continuing series, the first official RPMBT meeting, RPMBT-1, was held in Trieste in 1978,. A full list of the conferences held to date is as follows:

RPMBT_1:	Trieste, Italy; 1978 (2 - 7 October, 1978)
	The Local Organising Committee comprised: Claudio Ciofi degli Atti (Chair), Sergio Rosati, and Alpo Kallio.
	Some Highlights of the meeting: The conference was dedicated to the memory of Eugene Feenberg who, at an early stage of planning of this conference, was on the list of invited speakers, but who sadly died before the meeting took place. The clearly stated purpose of this first RPMBT conference was, as in all following meetings, to gather together people from different fields of many-body theory such as nuclear physics, quantum liquids and dense matter in order to help promote exchange of new ideas between the different fields . An example of such a development has been the hypernetted chain (HNC) theory of classical statistical mechanics which was first applied to quantum fluids and now also to nuclear many-body problems. This has become then a rather prominent subject at this conference. An excellent conference Summary Talk titled "Update on the Crisis in Nuclear-Matter Theory: A Summary of the Trieste Conference" was given by John Clark.
	The Proceedings of the conference were published in: Nuclear Physics A 328, Issues 1–2, Pages 1-600 (1 October 1979).
RPMBT-2:	Oaxtepec, Mexico; 1981 (12 - 17 January, 1981)
	The Local Organising Committee comprised: John W. Clark (Chair), Mauricio Fortes, Manuel de Llano, and John G. Zabolitzky.
	Some Highlights of the meeting: An idiosyncratic conference Summary Talk was given by Keith Brueckner.
	The Proceedings of the conference were published in: Recent Progress in Many-Body Theories, (eds. J.G. Zabolitzky, M. de Llano, M. Fortes and J.W. Clark), Lecture Notes in Physics, Vol. 142 (Springer-Verlag, Berlin, 1981).
RPMBT-3:	Odenthal-Altenberg, Germany; 1983 (29 August - 3 September, 1983)
	The Local Organising Committee comprised: Hermann Kümmel (Co-Chair), Manfred L. Ristig (Co-Chair), Charles E. Campbell, and Sergio Rosati.
	Some Highlights of the meeting: A concise but very incisive conference Summary Talk, which is included in the Conference Proceedings (see below), was given by Lou H. Nosanow. In his summary he states that: "The subject matter covered in this conference can be classified under the following four major headings: (1) systems of nucleons, (2) quantum liquids, (3) systems of electrons, and (4) techniques." He also farsightedly, and rather accurately, predicted future trends and opportunities in the field of quantum many-body theory.
	The Proceedings of the conference were published in: Recent Progress in Many-Body Theories, (eds. H. Kümmel and M.L. Ristig), Lecture Notes in Physics, Vol. 198 (Springer-Verlag, Berlin, 1984).
RPMBT-4:	San Francisco, California, USA; 1985 (12 - 17 August, 1985)
	The Local Organising Committee comprised: Roger A. Smith (Chair), Phil J. Siemens, and John G. Zabolitzky.
	Some Highlights of the meeting:
	The Proceedings of the conference were not published.
RPMBT-5:	Oulu, Finland; 1987 (3 - 8 August, 1987)
	The Local Organising Committee comprised: Alpo J. Kallio (Chair), Jouko Arponen, Risto Nieminen, Erkki Pajanne, and Chris J. Pethick.
	Some Highlights of the meeting: The meeting included a Panel Discussion, chaired by Neil W. Ashcroft, to consider the latest developments of the then extremely rapidly growing field of high-Tc superconductivity, after the discovery in the previous year of the ceramic cuprate superconductors by Karl Müller and Johannes Bednorz. At the meeting a presentation was made to Hermann Kümmel to mark his 65th birthday and his impending retirement from the Chair in Theoretical Nuclear Physics at Ruhr-Universität Bochum, at the end of a special Tribute talk by John Zabolitzky, titled "Professor Hermann G. Kümmel - 65 Years", which is included in the Proceedings (see below). A special Tribute talk was given by Ray Bishop, titled "Correlated Basis Functions and All That: A Tribute to John W. Clark, Recipient of the Second Feenberg Award", which is included in the Proceedings (see below). The conference Summary Talk, titled "Whither Many-Body Theory? - A Summary of the Oulu Meeting", was given by John Clark, and is included in the Proceedings (see below).
	The Proceedings of the conference were published in: Recent Progress in Many-Body Theories, Vol. 1, (eds. A.J. Kallio, E. Pajanne, and R.F. Bishop), (Plenum, New York, 1988).
RPMBT-6:	Arad, Israel; 1989 (5 - 10 November, 1989)
	The Local Organising Committee comprised: Yshai Avishai (Chair), Aron Lonke, Ora Entin, Hanoch Gutfreund, Yoseph Imry, Moshe Kaveh, and M. Revsen.
	Some Highlights of the meeting: A half-day Special Session was held on recent developments in high-Tc superconductivity, together with an evening Round Table discussion on the future of the field. This meeting was perhaps the first in the series at which several talks were given by experimentalists. Other Special Sessions were devoted to: (a) localization (including the propagation of waves in disordered media, and (b) the then rapidly growing area of mesoscopic systems. An excellent conference Summary Talk was given by Hermann G. Kümmel, which is included in the Proceedings (see below).
	The Proceedings of the conference were published in: Recent Progress in Many-Body Theories, Vol. 2, (ed. Y. Avishai), (Plenum, New York, 1990).
RPMBT-7:	Minneapolis, Minnesota, USA; 1991 (26 - 31 August, 1991)
	The Local Organising Committee comprised: Charles E. Campbell (Co-Chair), Eckhard Krotscheck (Co-Chair), Siu A. Chin, John W. Clark and J. Woods Halley.
	Some Highlights of the meeting: A lively and delightful talk entitled "L. D. Landau - His Life, Achievements and my own Memories" was was given by A. A. Abrikosov. For the first time in the Series the meeting included invited Overview Talks given by several eminent speakers on particular areas of interest. One day (Wednesday, 28th August) of the meeting was allotted to the Symposium on Large-Scale Computational Approaches to Many-Body Systems, which was held at the Minnesota Supercomputer Institute. Mal H. Kalos presented the Keynote Talk for the Symposium, which is included in the Proceedings (see below). The Conference Outing on the following day (Thursday, 29th August) comprised a delightful river cruise on the Mississippi that was "officially" described in the conference Summary Talk (see below) as: "The trip through the locks was the perfect recreation for weary physicists, who acted more like children than adults as the water level dropped 50 feet." The conference Summary Talk was given by A.L. ("Sandy") Fetter, and is included in the Proceedings (see below).
	The Proceedings of the conference were published in: Recent Progress in Many-Body Theories, Vol. 3, (eds. T.L. Ainsworth, C.E. Campbell, B.E. Clements, and E. Krotscheck), (Plenum, New York, 1992).

	The Local Organising Committee comprised: David Neilson (Chair).
	Some Highlights of the meeting: A Special Session was devoted to theories for many-electron systems in zero dimensions (quantum dots), one dimension (quantum wires), and two dimensions (electron layers). By the time of this meeting these low-dimensional electronic systems are firmly established as fertile sources of novel and challenging many-body phenomena. The conference was also the 7th in the University of New South Wales (UNSW) Series of "Gordon Godfrey International Workshops on Theoretical Physics". The late Gordon Godfrey was an Associate Professor at UNSW, who bequeathed his estate for the promotion and teaching of theoretical physics within the community. The conference was attended by 124 participants from 24 countries. The Proceedings of this conference form the inaugural volume of the Series on Advances in Quantum Many-Body Theory, published by World Scientific (Singapore) under the auspices of the International Advisory Committee of the RPMBT Conference Series.

	The Local Organising Committee comprised: Joaquin Drut (Chair), Gokce Basar, Amy Nicholson, Shailesh Chandrasekharan, Lubos Mitas, and Thomas Papenbrock.
	Some Highlights of the meeting: Due to the COVID-19 pandemic, which started in March 2020, the conference was postponed by one year: from September 2021, as originally planned, to September 2022. As a bridge to the actual conference, the Quantum Many-Body Days (QMBD) were organized as a series of online talks in September 2021. Speakers at QMBD included X.-G. Wen, X. Qi, R. Melko, F. Verstraete, H. Nishimori, M.J. Savage, S. Sachdev, and M. Metlitski. The actual RPMBT-21 conference was held in 2022 in Chapel Hill (in person), on the University of North Carolina campus, at the beautiful Carolina Inn hotel, an iconic historical landmark of the town. The conference was supported in part by UNC, Duke University, NCSU, Oak Ridge National Lab, and the U.S. National Science Foundation. As a special topic, two sessions were held on "Quantum Information and Matter" (broadly defined to include quantum computing, quantum magnetism, and related topics), reflecting the high level of activity in that area on the experimental, theoretical, and computational sides of many-body physics. For the first time, the Feenberg medal was awarded to three people (Antoine Georges, Gabriel Kotliar, and Dieter Vollhardt) (pictured below), for their development of dynamical mean-field theory and its application to elucidating the electronic properties of real materials. Probably for the first time, conference talks were given by several (about 8) students, all of which were excellent. Thanks to a generous donation from Lenovo, five laptop computers were awarded to the best student contributions: 3 for talks: (David Jansen, Francesco Marino, and Megan Moss) and 2 for posters (Cristian Apostoli and Tong Shen) (pictured below). Francesco Pederiva and Jordi Boronat formed an ad hoc committee for this purpose.
	The Proceedings of the conference were not published, but copies of the slides from many of the talks can be found here.

The general format and style of the conferences have undergone some changes that have reflected the developments of the field since its inception. At the first meeting, much excitement came from the development of several new methods for the quantum many-body problem. At a time where the community largely considered the field as "mature", new impetus came from realizing that not all was well with the many-body problem. This realization, first vocalized and brought to the attention of the community by John Clark, became known as the crisis in nuclear-matter theory. It arose when the variational results for the ground-state energy of nuclear matter, obtained from low-order variational calculations using Jastrow-correlated trial wave functions, were found to lie significantly below the corresponding results obtained, with the same nucleon-nucleon potentials, from lowest-order Brueckner theory in the perturbative framework. The resolution of this crisis taught us much about both of the main technological branches of quantum many-body theory, namely the variational-theoretic and the perturbation-theoretic, and the interrelations between both. John Clark gave a Summary Talk at RPMBT-1 in which he focused on giving an update on the crisis in nuclear-matter theory, including a recap of the problem.

Even more importantly, it led to the creation of a common language through which the practitioners in these previously quite disparate branches could communicate with, and learn from, each other. The first few meetings of the series were the forum where the "second-generation" many-body theories were publicized and discussed: fully optimized Jastrow-Feenberg and CBF methods, a tremendous development of coupled cluster theory (the "extended coupled cluster method"), parquet-theory and, last but not least, stochastic methods which took advantage of the availability of ever-increasing amounts of computational power. This quest for a common language has remained a great unifying strength ever since. The early meetings in the RPMBT series also taught us that such existing techniques as correlated basis function theory and the coupled cluster method were already both extremely versatile and very accurate in practice. We learned too that what seemed to be needed much more than new techniques were better and more powerful systematic truncation or approximation hierarchies, based on the physics of the system to which they were being applied, and possibly also on marriages between existing methods.

Broadly speaking, there are two types of contributions to many-body theory. On the one hand there are those devoted to the development of new methods and techniques, and the refinement of existing ones. On the other hand there are those contributions which seek to understand and to explain emergent many-body phenomena in particular systems. Such systems themselves may be either highly simplified models, for which various exact results often play a key role, or more or less close representations of actual physical systems, for which extensive numerical computations are usually required. The earliest meetings in the series, up to and including RPMBT-3 at least, were largely characterized by concentrating on techniques rather than on specific problems. The most active fields of application were the nuclear many-body problem and the quantum fluids ³He, ⁴He and their mixtures.

Over the years, the focus shifted somewhat from many-body techniques to many-body phenomena. By the time of RPMBT-4, held in San Francisco in 1985, although nuclear problems and quantum fluids remained the main test-beds of many-body methods, a more visible response to recent experimental developments was apparent. Such topics as the quantum Hall effect, heavy fermions, Anderson localization, and the quark-gluon plasma became the foci for debate. With hindsight, RPMBT-5 in Oulu in 1987 was probably the first meeting in the series in which there was enough apparent confidence in the tools of quantum many-body theory to stress more their ability to be widely applied to the newer and less traditional fields of application. Very soon after the discovery in 1986 by Bednorz and Müller of the high transition-temperature superconductivity in the ceramic cuprate materials, applications of quantum many-body methods to them were being discussed at RPMBT-5. By the time of RPMBT-6 in Arad in 1989 the Hubbard model and its variants were firmly ensconced on the agenda.

Since RPMBT-5 recurring themes have included heavy fermions, the quantum Hall effect, disordered systems, localization, complex systems and chaos, mesoscopic systems, and the development and application of quantum Monte Carlo methods. Sessions on lattice Hamiltonian problems and strongly correlated electronic systems have become particularly firm fixtures. At the same time new twists on such old friends as quantum fluids and nuclear and subnuclear matter have continued to surprise and delight us, and many of these have been recorded in recent proceedings of the RPMBT series, together with other such topical sessions as Bose-Einstein condensates and quantum dots and chaos, and such old friends with renewed vigor as density functional theory. Other recent topics have included new developments in biological physics, quantum computing and allied areas of quantum information theory, and quantum control.

A major challenge of meetings since around RPMBT-10 has been to define and explore the important areas of overlap of quantum many-body theory with quantum field theory and, increasingly, with statistical physics, in such likely arenas as

• phase transitions and the related competing effects of quantum versus thermal fluctuations
• spontaneous symmetry breaking
• the unifying role of gauge invariance (and perhaps other symmetries)
• concepts from complexity theory, including the role of correlations and fluctuations in complex systems, and the competition between analysis and synthesis as modes of understanding many-body systems
• entropy and its generation and flow
• quantum information theory and quantum computation

The first talks involving machine learning in quantum many-body theory appeared around the time of RPMBT-21.

Feenberg Memorial Medal

Feenberg Medal

The Eugene Feenberg Memorial Medal (or Feenberg Award) was established by the many-body physics community at the Third International Conference on Recent Progress in Many-Body Theories (RPMBT-3) in 1983 as a continuing memorial to Eugene Feenberg. It commemorates his wise stewardship of a field that penetrates into all branches of physics; his deep physical insights and great formal achievements; his dedicated service as teacher and mentor; and the exemplary integrity of his personal and professional life. The Feenberg Award thus serves to preserve the memory of the unique and enduring contributions of Eugene Feenberg to physics, especially to the foundations of nuclear physics and the microscopic quantum many-body physics of nuclei and quantum fluids.

The Eugene Feenberg Medal is awarded under the auspices of the International Advisory Committee of the series of International Conferences on Recent Progress in Many-Body Theories. The Feenberg Medal, first awarded in 1985, is designated for work that is firmly established and which can be demonstrated to have significantly advanced the field of many-body physics. The work considered can be accumulative contributions sustained over time, or a single important contribution. In appropriate cases, the award can be shared by as many as three people for a single body of work. The Feenberg Award Rules are listed below.

Past recipients have included Walter Kohn (1991) and Anthony J. Leggett (1999), both of whom later won a Nobel Prize for their work, in 1998 and 2003, respectively.

A full list of Feenberg Medallists is given below, together with their respective citations.

Feenberg Award Rules

In the following, the "Advisory Committee" means the "International Advisory Committee of the Series of International Conferences on Recent Progress in Many-Body Theories," and the "International Conference" or "Conference" means the "International Conference on Recent Progress in Many-Body Theories."

I. General Rules:

A. The Feenberg Medal, or Feenberg Memorial Medal in Many-Body Physics, may be awarded for an important contribution or contributions to many-body theory.

B. In selecting recipients of the Medal, there will be no discrimination based on sex, age, race, nationality, religion, or political beliefs.

C. Members of the operative Selection Committee and their families and relatives are not eligible for receipt of the medal.

II. Award Ceremony:

A. The Medal will be awarded approximately every two years. The ceremony for awarding the Medal will be held at the International Conference for as long as these Conferences exist and retain a format similar to that of the first four Conferences. Thereafter the Advisory Committee should make appropriate arrangements for perpetuating the award and preserving its spirit.

B. The Selection Committee will organize the ceremony in collaboration with the organizers of the Conference. The recipient of the award will be invited by the Conference organizers as an invited speaker.

C. The tribute to the awardee will be published in the proceedings of the Conference (whenever available) at which the Feenberg Medal was awarded. In the same proceedings an updated list of patrons, sponsors, and contributors is to be published.

D. Award dates will be fixed by mutual agreement of the Selection Committee (see below) and the Advisory Committee.

III. Selection Committee:

A. The Selection Committee that will decide on the award to be granted at the next Conference, and the Chairperson of that Selection Committee, are to be appointed by the Advisory Committee at each International Conference.

IV. Duties of the Selection Committee:

A. The Chairperson of the Selection Committee will organize the work of that Committee according to the present Rules and Procedures (see below).

B. The Selection Committee will organize, with the agreement of the Advisory Committee, the publicity for collecting proposals for the recipient of the Medal.

C. Only one award will be given at each Conference, which award should be given preferably to one person, but to no more than three persons, and in any case for a single corpus of work.

D. All of the deliberations of the Selection Committee in reaching their decisions will be kept confidential, except in so far as is deemed necessary to inform the Advisory Committee, who will in turn keep them entirely confidential.

E. The Selection Committee is charged with preparing a citation for general circulation, describing the achievements of the recipient or recipients which led to the award.

V. Procedures:

A. The Advisory Committee will from time to time set and review the operating procedures to interpret the Rules and to be followed by the Selection Committee in the performance of their work. Any such procedures may be kept confidential or made public at the discretion of the Advisory Committee.

VI. Rule Changes:

A. Any proposal for changing these rules should be advanced to the Advisory Committee by six months prior to its next meeting.

Some of the current Procedures adopted under Rule V for the Feenberg Award are:

1. Rule I.A will be construed such that each Feenberg Medal will be awarded for work that is firmly established and that can be demonstrated to have significantly advanced the field of theoretical many-body physics. While such impact may be easier to demonstrate for a nominee whose contributions span a considerable period of time than for a nominee who has made a single important contribution, both cases will be considered.

2. Rule IV.C will be construed such that each award may, in appropriate cases, be shared by up to three persons for a single or closely linked body of work. However, sharing the award will always be considered exceptional rather than the norm. A case must be truly compelling to offer the award to three persons.

3. Any complete case submitted to a Selection Committee for the award shall contain all of the following:

• A letter of nomination summarizing the most important research contributions of the nominee. This letter should not be more than four pages in length. Up to three other letters of support may also (and preferably should) be submitted at the same time.

• The nominee's publication list, citing the most significant 3 to 5 publications first, separated from the rest.
• A recommended citation, preferably of 30 words or less.
• The nominator's email address and telephone number.

4. Any complete case for a nominee or set of nominees for the award will be considered by successive Selection Committees a maximum of three times. Thereafter, no case for the same nominee or set of nominees will be considered again unless for a completely different corpus of work.

Brief Biography of Eugene Feenberg

Eugene Feenberg; October 6, 1906 — November 7, 1977

Photograph in the Obituary in Nucl. Phys. A 317 (1979).

Born October 6, 1906 in Fort Smith, Arkansas, Eugene Feenberg received a B.A. in physics and M.A. in mathematics in 1929 from the University of Texas, Austin after three years of study. After a year and a half traveling in Europe as a Parker Traveling Fellow, visiting the groups of Sommerfeld, Pauli, and Fermi, he received his Ph.D. in 1933 from Harvard University, where his thesis advisor was E. C. Kemble. His thesis included the first statement and proof of the quantum optical theorem.

Subsequently Feenberg was Instructor or Fellow at Harvard, Wisconsin, and the Princeton Institute for Advanced Studies, during which time he collaborated with Wigner, Bardeen, Breit and Phillips among others. After eight years on the faculty of New York University and four years during World War II at Sperry Gyroscope, Feenberg joined the faculty of Washington University (St. Louis) in 1946, and in 1964 became the Wayman Crow Professor of Physics, a chair previously held by Arthur H. Compton, Arthur L. Hughes, and Edward U. Condon.

Much of Feenberg's early research was concerned with the theory of the nucleus, culminating in the publication of Shell Theory of the Nucleus by Princeton University Press in 1955. While he had a career-long interest in perturbation theory, he turned his primary focus to the theory of quantum fluids, most notably the helium liquids, toward the end of the 1950's, a subject to which he would contribute very importantly for the next two decades until his death in 1977 . Along with his students, he developed the method of correlated basis functions in order to deal with the strong, short-range repulsion between helium atoms that makes the theory of the helium fluids virtually intractable using ordinary perturbation theory. The early part of this research is the subject of his monograph Theory of Quantum Fluids (Academic Press, 1969).

His willingness to tackle the challenge of strong, short-range correlations by developing a theoretical, ab initio framework to deal with them from first principles, characterizes much of Feenberg's research. As important as his research is, his personal integrity and high principles continue to serve as an inspiration for his former students and colleagues. The awarding of the Eugene Feenberg Memorial Medal serves as an opportunity to commemorate and perpetuate this man's unique influence on physics and physicists.

It is noteworthy that Issue 1 of Volume 317 of the journal Nuclear Physics A, published on 2 April 1979, is an invited volume dedicated to the memory of Eugene Feenberg. As the opening editorial pages record: "The first issue of this volume (pp. 1-286) is composed of papers dedicated to the memory of the late Professor Eugene Feenberg." The issue then begins with an obituary, signed by Keith Brueckner, Chuck Campbell, John Clark, and Henry Primakoff, which ends with a list of Feenberg's publications. The obituary also includes a photograph of Feenberg in front of a chalkboard, which is reproduced here to the right.

The reader interested in more details of Feenberg's life and legacy may find some in a talk by John W. Clark, entitled The Legacy of Eugene Feenberg at the Centenary of His Birth, which is included in the Conference Proceedings of RPMBT-13. This article also includes a splendid photograph of Eugene Feenberg in conversation with Joseph Hirschfelder and Richard Norberg, which was taken in the Pfeiffer Physics Library during the 1974 Washington University symposium that celebrated Feenberg's career.

Kümmel Early Achievement Award

The International Advisory Committee responsible for the International Conference series on "Recent Progress in Many-Body Theories" and for awarding the Feenberg Medal, decided at the Thirteenth International Conference on Recent Progress in Many-Body Theories (RPMBT-13) in 2005 to establish a new award for young physicists whose published work is a significant contribution to quantum many-body theory. The Kümmel Award Rules are listed below.

The title of this award, "THE HERMANN KÜMMEL EARLY ACHIEVEMENT AWARD IN MANY-BODY PHYSICS", honors Prof. Kümmel's long and distinguished career as a leader in the field and as a mentor for younger generations. It should be noted that Prof. Kümmel, together with Prof. Raymond Bishop, received the Feenberg Memorial Medal in 2005 for development of the coupled cluster method.

A full list of Kümmel Awardees is given below, together with their respective citations.

Brief Biography of Hermann Kümmel

Hermann Kümmel; October 7, 1922 — May 16, 2012

Hermann Kümmel was born in 1922 in Berlin. After obtaining his Diploma degree in 1950 from Humboldt University in East Berlin, he received the Ph.D. in Theoretical Physics from the Free University in West Berlin, where he continued with his research until moving to Iowa State University in Ames, Iowa, USA as a research associate. It was during his two years in Ames that, in collaboration with Fritz Coester, the foundations were laid for the birth of the coupled cluster method (CCM) for which he later became renowned. In 1960, Professors Kümmel and Coester published their seminal ideas of the CCM in the journal Nuclear Physics. After periods at the University of Tübingen, the Max Planck Institute for Nuclear Chemistry in Mainz and the University of Mainz, and at Oklahoma State University as Professor of Physics, Professor Kümmel returned to Mainz as senior scientist at the Max Planck Institute, where he built a strong research group, and Adjunct Professor at the University of Mainz.

In 1969 Professor Kümmel moved with his entire research group to a Chair in Physics at the newly established Ruhr University in Bochum (RUB), Germany, where he established RUB as one of the world's leading centers in quantum many-body theory. In particular, it was at this time that he turned his attention to the theoretical development and computational application of the CCM to nuclear systems specifically and fermionic systems in general. The level of sophistication achieved in Bochum under his leadership, in both formal and computational strength, has rarely been matched elsewhere.

He retired in 1988 at the mandatory retirement age, retaining his association with RUB as Professor Emeritus. To mark his achievements in the field he was also elected as the first Honorary President of the International Advisory Committee for this RPMBT series of international conferences.

The reader interested in more details of Kümmel's life and legacy may find some in a talk entitled A Tribute to Hermann Kümmel on his 80th Birthday, which is included in the Conference Proceedings of RPMBT-11.
