Summary
Metastability is a ubiquitous phenomenon in nature, with examples coming from physics, chemistry, biology, climatology and economics. The object of interest is the evolution of systems that make transitions between "metastable states", i.e., quasi-equilibria that appear to be equilibria on large time scales. When being in such a metastable state, the system explores a confined section of the phase space on a short time scale, and makes transitions between different sections on a large time scale. The goal is to develop a mathematical theory for such behavior.
Two approaches have been very successful. One is the pathwise approach, in which the evolution of the system is described with the help of large deviation theory and detailed statements are obtained about the trajectories of the system before, during and after the transition. The other is the potential theoretic approach, in which the system is viewed in an electric network context and transition times are computed in terms of capacities.
The workshop will focus on systems of spins and particles subject to a stochastic dynamics governed by a model Hamiltonian. Examples are Glauber dynamics for Ising spins, Kawasaki dynamics for lattice gas particles, and probabilistic cellular automata.
It is challenging to develop metastability in a broad context, clearing out what parts of the theory are general and what parts are model dependent. Universality is a key notion, with many systems showing similar behavior on large time scales. Much work focusses on the geometry of critical droplets that trigger the metastable cross over and on the tube of trajectories towards the cross over.
Simulations of metastability are hard to perform in a reliable manner, but are helpful in leading the way to understand new phenomena.
