WORKSHOP on CRITICAL STABILITY  (first circular)



An international workshop on "Critical stability of few-body quantum
systems" will be held at (MPIPKS) the Max-Planck-Institut f\"{u}r
Physik Komplexer Systeme in Dresden, Germany on October 17-22, 2005.
We shall try an intensive program of one weeks extension, beginning
monday morning with a break wednesday afternoon and closing friday
evening with a dinner party.  As the planning proceeds more
information will be accumulated on http://www.mpipks-dresden.mpg.de

Three previous international and interdisciplinary workshops on
critical stability took place at ECT* in Trento in February 1997, at
Les Houches in October 2001 and at Trento September 2003. The summary
of the first Trento workshop can be found at
http://ect.it/rep\_97/CSFBS.html.  The proceedings from Les Houches
are published in Few-Body Systems vol 31, 73-266, and proceedings from
Trento 2003 are published in Few-Body Systems vol 34, 1-208.

The idea of these workshop originates in the observation that almost
all subfields of physics apply similar methods to study similar
few-body problems at the edge of stability. The usual meetings do not
often appeal to the interdisciplinary aspects of the common concepts
and techniques. We want to continue in the same spirit as these
previous workshops where various subfields like quantum chemistry,
mathematical, atomic, molecular and nuclear physics were represented
by lively participants from many different countries.

The focus of the present workshop at MPIPKS in October 2005 will be on
the properties of weakly bound quantum states and resonances near
threshold. The specific emphasis will be influenced by the interests
of the participants. The topics within the main theme will include:

1. Weakly Coulomb or gravitational-bound few-body states.
2. Weakly short-range-interaction bound few-body states.
3. Continuum structure and few-body decay properties.
4. Dynamical few-body problems near instability.
5. Correlation in boson-fermion and mixed condensates
6. Few-body correlation within many-body systems.
7. Exotic structures: Efimov, tango, Samba, Borromean, halo states.
8. Lower-dimensional systems.
9. Semi-classical methods.

Details about the workshop.


The workshop will consist of a number of talks and some poster
sessions.

Abstracts will be collected and made available before or at the
beginning of the workshop.

Proceedings are planned to appear in one issue of Few-Body Systems
with normal refereeing of the papers.  To ensure fast publication the
submission deadline will be November 12, 2005, i.e. a few weeks after
the workshop.

The total number of participants are limited to about 60. Participation
is only by invitation.  Accomodation will be arranged and local
expenses for lodging and meals will be covered by MPIPKS.  The
registration fee is 100 Euro covering excursion, conference dinner,
coffee, etc. Limited fund for travel expenses is available.

Participation can be requested by writing to the scientific
coordinators (copies to both), see addresses below.  If oral and/or
poster contribution is requested both title and a one-page abstract
should be supplied.  A number of speakers will be chosen among these
applicants.

Speakers will be asked to keep in mind that the participants come from
different fields of physics. The level is then suitable for mature
phd-students, postdoctoral fellows, other young scientists as well as
established physicists wishing to broaden their knowledge.  We hope a
number of groups will take the opportunity and send members for a
general update on the developments in other fields with sufficient in
common to be worth the effort.

Early indication of interest would help in the organization of the
program and increase the chances for an oral contribution. Some
speakers filling out gaps in the intended program will be chosen along
the way. Otherwise the deadline for titles and abstracts for speakers
and participants is preliminarily set to April 30, 2005.
