Molecular Simulation in the 21st Century

2nd-5th July 2000, University of Surrey

This annual meeting of CCP5 will review the progress made in various branches of what is loosely referred to as 'molecular simulation', and to discuss prospects for and to identify areas that are likely to become of central importance in the not too distant future. The particle-based simulation of liquids, solids and granular materials will be included in the programme. Special attention will be given to methods for expanding the scope of molecular simulation techniques to shorter/longer time and length scales, e.g. biased sampling schemes in Molecular Dynamics and Monte Carlo, and coarse-graining procedures. The plenary lectures will include

The local organizers are Prof. David Heyes (Chemistry) and Dr Sebastian Reich (Mathematics). Further details about registration and the programme can be found at the website:

International Workshop on Fluctuations and Superfluidity

2nd-3rd September 2000, Lancaster, UK

Nonequilibrium fluctuations pervade almost all areas of science. They lie at the root of many fundamental concepts of statistical physics and are responsible for e.g. quantum tunnelling giving rise to vortex creation in superfluid helium, cosmic strings in the early universe, chemical reactions, and important phenomena in nonlinear dynamical systems, physiology, and two-dimensional electron assemblies - as well as impacting on social and economic problems. The purpose of the proposed workshop is to bring together a group of scientists that do not normally meet or communicate, but all of whom work on nonequilibrium fluctuations. They will be drawn from UK, Italy, Spain, Germany, USA, Slovenia, Ukraine and Russia. Major points of emphasis will be on macroscopic quantum tunnelling as representing one of the most (if not the most) fundamental types of fluctuation, and on helium superfluidity which provides a unique tool for investigating such fluctuations. Leading specialists working on quantized vortex creation, and fluctuational phenomena in 2D-electron systems on the superfluid surface will meet - in most cases for the first time -with fluctuational dynamicists. The meeting will thus provide a unique opportunity for direct discussion between two distinct scientific communities. It will therefore facilitate a search for possible breakthroughs in the understanding of large fluctuations in systems far from thermal equilibrium.

First Mathematics in Medicine Study Group

11th-15th September 2000, University of Nottingham

The aim of this meeting is to bring together applied mathematicians and biomedical researchers to work on problems of mutual interest. The format of the Study Group will be based on that successfully developed in the Study Groups with Industry, to which problems are brought be industrial workers. The issues to be addressed will be presented by the biomedical participants and discussed with the organisers prior to the meeting to ensure that they are amenable to mathematical study. It is anticipated that the resolution of many of the problems brought to the Study Group will lead to journal publications and foster longer-term multi-disciplinary collaborations between mathematical and biomedical researchers. We are compiling a database of pertinent research expertise and all those interested in the application of mathematics in medicine are invited to send contact details and up to six keywords describing their research interests to for inclusion. Limited financial support will be available to suitable participants. Registration information will appear at nearer to the event; expressions of interest at this stage are very welcome.'

Integrable Systems

July to December 2001, Newton Institute (Cambridge)

The modern theory of integrability was created and developed over the last thirty years by a number of international research groups. Several approaches to integrable equations have been elaborated, which look quite different but focus on solutions of the same range of problems. One of the aims of this programme is to bring together key scientists with various background and expertise in order to elaborate a coherent view on the problem and to attempt to develop a synthetic theory which would reconcile the different approaches. This will be the first meeting on such a scale and we expect that mutual understanding of different approaches will cause a breakthrough in the whole theory of integrable equations and significantly extend its applications.

The following methods for studying integrability will be discussed

In addition the "dressing method", and its many variations, will be looked at as a technique for constructing and solving integrable systems. The topic of Quantum Integrability will also be addressed. Links between the classical dressing method and various approaches to quantum systems will be studied. A fundamental issue is a classification of algebraic and differential reductions ``inside'' the integrable systems which have been constructed.
