PREFACE
The Thirteenth International Conference on Recent Progress in Many-Body The
ories (RPMBT-13) was held at the University of Buenos Aires, Buenos Aires, Ar
gentina, 5-9 December 2005. The present volume contains most of the invited talks
plus a selection of excellent poster presentations.
This conference series is now firmly established as one of the premier series of
international meetings in the field of Many-Body physics. The first official RPMBT
meeting was held in Trieste in 1978, in response to several precursor meetings that
accentuated the need for a continuing series. The most important of these, which
can be regarded as RPMBT-0, is the 1972 conference on The Nuclear Many-Body
Problem organized by F. Calogero and C. Cioffi degli Atti in Rome. Additionally,
there were two very significant workshops held in 1975 and 1977 at the Univer
sity of Illinois, Urbana, with Vijay Pandharipande as the chief organizer. The
quantum many-body community suffered a profound loss with Pandharipande's
untimely death in early 2006. Later conferences in the series have been the 1981
RPMBT-2 meeting in Oaxtepec, Mexico; the 1983 RMPBT-3 meeting in Altenberg,
Germany; the 1985 RPMBT-4 meeting in San Francisco, USA; the 1987 RPMBT-5
meeting in Oulu, Finland; the 1989 RPMBT-6 meeting in Arad, Israel; the 1991
RPMBT-7 meeting in Minneapolis, USA; the 1994 RPMBT-8 meeting in Schloss
Seggau, Styria, Austria; the 1997 RPMBT-9 meeting in Sydney, Australia; the 1999
RPMBT-10 meeting in Seattle, USA; the 2001 RPMBT-11 meeting in Manchester,
UK; the 2004 RPMBT-12 meeting in Santa Fe, USA, and the present 2005 meeting
in Buenos Aires. Highlights of past meetings can be found in earlier volumes of this
series.
This conference series is also responsible for awarding the prestigious Eugene
Feenberg Memorial Medal in Many-Body Physics. This medal, first presented in
1985, is designated for work that is firmly established and that can be demonstrated
to have significantly advanced the field of many-body physics. Past recipients have
included David Pines (1985), John W. Clark (1987), Malvin H. Kalos (1989), Wal
ter Kohn (1991), David M. Ceperley (1994), Lev P. Pitaevskii (1997), Anthony
J. Leggett (1999), Philippe Nozieres (2001), and Spartak T. Belyaev and Lev P.
Gor'kov (2004). Professors Kohn and Leggett received the Nobel Prize in 1998 and
2003 respectively. We are pleased that the Tenth Feenberg Medal was awarded
at this conference to Professors Hermann Kummel and Raymond Bishop for their
development and application of the Coupled-Cluster Method to diverse physical
problems. During the past half century, the application of this quantum many-body
physics approach has contributed substantially to our understanding of challenging
problems in condensed matter physics (including electrons in solids, nuclear mat
ter, quantum liquids and gases, and quantum magnetism), atomic and molecular
physics, nuclear physics, and subnuclear physics/quantum field theory (see R.F.
Bishop and H. G. Kummel, "The Coupled-Cluster Method," Physics Today, March
1987). The Coupled-Cluster Method is one of very few ab initio methods that has
an enduring impact in quantum chemistry. The presentation was made by Charles
IX
