NEW BOOK BY PROFESSOR BERNARD PAGEL
The book `Nucleosynthesis and Chemical Evolution of Galaxies' by Bernard Pagel
has been published by Cambridge University Press. Based on a course of
lectures given at Copenhagen University, it gives an account of thermonuclear
reactions, observed cosmic abundances of elements, primordial nucleosynthesis,
stellar evolution, neutron capture processes, models (mainly analytical) for
the chemical evolution of our own and nearby galaxies, nuclear
cosmochronology, background radiation and cosmic chemical evolution at high
red-shifts.
BOSE-EINSTEIN CONDENSATION IN DILUTE GASES
Nordita lecture notes from a course given by Henrik Smith and Chris Pethick on
the above subject are in the process of being printed. Copies may be obtained
from Nordita by contacting Jette Nielsen, email: nielsen@nordita.dk.
NORDIC PROJECTS AND CORRESPONDING FELLOWS 1997/98
At its board meeting on 13 -14 June 1997, Nordita's board decided to support
the following new Nordic projects: ``Semiclassical Methods in Quantum Field
Theory'', organizer D. Diakonov, Nordita; ``The Physics of Very Cold Atomic
Systems'', organizer C.J. Pethick, Nordita; ``Hot Non-Perturbative Particle
Physics'', organizer K. Rummukainen, Nordita; ``Statistical Mechanics of
Non-Equilibrium Systems'', organizer K. Sneppen, Nordita. The support is
granted for a period of 1 year. In addition, H. Fogedby, Aarhus University, and
A. Hansen, Trondheim, were each awarded a corresponding fellowship for a
duration of 12 months in 1997/1998. Below we present descriptions of the four
new projects and the new corresponding fellows.
Semiclassical Methods in Quantum Field Theory
At its meeting on June 13-14 1997, Nordita's Board decided to support a new
Nordic project ``Semiclassical Methods in Quantum Field Theory". Its
participants are D.Diakonov (Nordita, project leader), J.Ambjoern (NBI),
T.Jonsson (Reykjavik), A.Niemi (Uppsala), V.Petrov (St.Petersburg), M.Polyakov
(Bochum) and O.Tirkkonen (Nordita).
Semiclassical methods have been of the utmost importance in almost all
branches
of quantum physics and in quantum field theory in particular. The scientific
goals of the project are twofold: on one hand we plan to deepen the knowledge
about the semiclassical methods in quantum field theory, in particular to
investigate their relation to exactly solvable or integrable systems; while on
the other hand we plan to broaden the applicability of semiclassical methods
to new fields, like gravitational instantons or the relation of the
Yang--Mills instantons to confinement. For more information, contact the
project leader: D. Diakonov, email: diakonov@nordita.dk.
Nordic Project on the Physics of Very Cold Atoms
Since the experimental realization of Bose-Einstein condensation in alkali
atom vapors, there has been an explosion of interest in the physics of cold
atoms, and the properties of clouds of cold atoms. Under this project it is
planned to attack various problems in this general area, including collective
behaviour of atoms in the Bose-Einstein condensates (excitations and
vortices), cold binary collisions between laser-cooled atoms, and tailored
light fields that are important in optical lattices (and other specially
tailored light fields that are important in atomic optics). A number of groups
in the Nordic countries have interests in these problems, and a major aim of
the project is to foster collaboration between groups approaching problems
from somewhat different directions. Members of the network include: N.O.
Andersen, K. Moelmer, H. Smith, S. Stenholm, A. Svane, K.-A. Suominen, and K.
Berg-Soerensen. If you are interested in participating in the project, contact
the coordinator, Chris Pethick. (pethick@nordita.dk)
Hot Non-perturbative Particle Physics
The aim of this project is to study the physics of the Standard Model of strong
and electroweak interactions and its extensions at high temperatures and energy
densities -- conditions which can be found during the first fractions of a
second after the Big Bang, inside neutron stars, and, on Earth, in heavy-ion
collision experiments. The Big Bang provides the ultimate particle physics
experiment available to us: we can calculate the thermodynamical properties of
our favourite theories with, for example, lattice Monte Carlo methods, insert
the results into phenomenological calculations and weigh the outcome against
the observational data. This can lead to stringent tests of the Standard
Model, and point to theories beyond it.
For several years, the Nordic countries have given very strong contributions to the understanding of the physics of the matter at ultrahigh temperatures and densities. This project will bring together 22 physicists from Copenhagen, Helsinki, Stockholm, Uppsala, Gothenburg and Trondheim. The research interests include: cosmological baryon number violation and baryogenesis, magnetic fields in the early Universe, thermodynamics and phase transitions in the Standard Model, and the physics of supersymmetric theories at high temperature. Since these are often dominated by non-perturbative processes, a large part of the planned research is done with numerical lattice Monte Carlo methods.
The project starts in January 1998 and lasts until the end of the year 2000.
In addition to the scientific aspect of the project, during 1998-1999 the
project will organize (in collaboration with the NorFA-project `Standard model
in the Extreme Environments') a PhD school about the physics of the Standard
Model and its extensions at high temperatures and densities.
For more information, you are welcome to contact the project coordinator,
Kari Rummukainen at Nordita (kari@nordita.dk), and to visit our soon-to-appear
homepage at Nordita (http://www.nordita.dk/).
Nordic Network in Statistical Physics of Non-equilibrium Systems
The purpose of this Statistical-mechanics network is to catalyze Nordic
activities within the physics of non-equilibrium behaviour and complex systems.
In particular we consider the dynamics of large systems, examplified by
unfolding of instabilities in glassy and driven diffusive systems and
folding/unfolding dynamics of complex molecules such as proteins. A number of
such studies have recently been initiated within the Nordic area, including
the paper burning experiments by Timonen and coworkers in Jyvaeskylae,
the fracture front propagation experiment by M{\aa}l{\o}y and coworkers in Oslo
and the study of continuous unfolding of dynamic instabilities of growing
yeast colonies by Sams in Copenhagen, and finally the protein
folding/unfolding experiments by Zocchi at the Niels Bohr Institute.
The members of the network (Tapio Ala-Nissilae, Erik Aurell, Hans Fogedby,
Alex Hansen, John Hertz, Mogens Hoegh Jensen, Kristian Lindgren, Knut
Joergen M{\aa}l{\o}y, Carsten Peterson, Kim Sneppen and Jussi Timonen) are
currently working on problems in statistical mechanics, in particular related
to the understanding of the non-ergodicity of non-equilibrium systems. The
pathways that such systems tend to select during their evolution open up new
physics related to the interplay between dynamics, structure and function.
The network will meet for the first time for a small workshop at Nordita the
28-29 November 1997. Guests, in particular Nordic students, are welcome to
attend. Please contact John Hertz (hertz@nordita.dk) or Kim Sneppen (at
sneppen@nbivax.nbi.dk) for details.
