Statistics Seminars: Condensation and metastability in stochastic particle systems
31 October 2011 14:00 in CM221
We study zero-range and inclusion processes where particles move on a lattice according to a simple on-site or nearest neighbour interaction. The processes exhibit a condensation transition, where a finite fraction of all particles accumulates on a single site when the total density exceeds a critical value.
This has been understood on a rigorous level using results from large deviations for subexponential random variables. I will give a short account of those results and talk about some recent developments regarding the metastable dynamics in the condensed phase.
This is joint work with Ines Armendariz, Michalis Loulakis and Paul Chleboun.
