INHOMOGENEOUS RANDOM SYSTEMS Tuesday 25 and Wednesday 26 January 2011 - Schedule ESPCI 10, rue Vauquelin Paris Institut Henri Poincaré 11, rue Pierre et Marie Curie Paris

SHEPI

The aim of this annual workshop, in conjunction with the "Rencontres de Physique Statistique", is to bring together mathematicians and physicists working on disordered or random systems, and to discuss recent developments on themes of common interest. Each of the two days is devoted to a specific topic; the 2011 session is planned as follows.

Tuesday 25 January (ESPCI):
Kinetically constrained spin models, glasses and coalescence processes.
Moderators: Fabio Martinelli (Roma) and Cristina Toninelli (Paris)

Kinetically constrained spin models (KCSM) are interacting particle systems with Glauber type dynamics. The key feature is that the creation/annihilation of a particle can only occur if the current configuration around the site satisfies a certain local constraint. KCSM have been introduced in the '80 in physics literature to model liquid/glass transition and more generally the slow glassy dynamics occurring in several systems which undergo an arrest of their dynamics towards an amorphous state.

The aim of this day will be to present on the one hand the relation among KCSM and the physical systems which display a glassy dynamics, on the other hand to explore some recent mathematical developments on the out-of-equilibrium dynamics of KCSM and their connection with certain coalescence processes (aging, dynamical phase transitions, anomalously long mixing times...).

Speakers: J. Bertoin (Paris), G. Biroli (Saclay), T. Bodineau (Paris), B. Derrida (Paris), A. Faggionato (Roma), P. Sollich (London).

Wednesday 26 January (IHP):
Fast and slow, adiabatic and geometric effects in nonequilibrium dynamics.
Moderator: Christian Maes (Leuven)

A multicomponent dynamics often consists of quite different degrees of freedom, changing on separated scales of time or energy. We have in mind here large classical or quantum systems subject to driving or time-dependent dynamics, and where slow and fast variables can be identified. There we find the origin of standard methods of mathematical physics such as the Born-Oppenheimer approximation, the WKBJ-method and the adiabatic theorem. This conference day will be devoted to some recent developments in transport and diffusion processes treating stochastic and quantum pumping, adiabatic computation and non-equilibrium adiabatic theorems, geometric and topological effects and corrections to the weak coupling limit.

Speakers: Y. Avron (Haifa), N. Berglund (Orléans), G. M. Graf (Zürich), R. MacKay (Warwick), K. Netočný (Praha), W. De Roeck (Heidelberg), S. Shlosman (Marseille).
