Title: Large deviations and metastability in condensing stochastic particle systems
Abstract:
Condensation, or jamming transitions, are observed throughout the natural and social sciences as prevalent emergent phenomena in complex systems, from shaken granular gases to traffic congestion. Considerable insight into the basic mechanisms of such phenomena can be gained by studying stochastic particle systems. In this talk, we will discuss a general approach to understanding phase separation and metastability in stochastic particle systems that exhibit a condensation transition. These methods will be exemplified by analysis of the finite-size effects in a condensing zero-range processes. We find the free energy landscape associated with the condensate, which in turn implies different mechanisms for the metastable dynamics of the condensate, depending on the system parameters.
