Title: Large deviations and metastability in a zero-range process
Abstract: We demonstrate a general approach to understand the role of finite size effects and metastability in complex systems by application to a simple toy model. We study a zero-range process where the jump rates do not only depend on the number of particles on a site, but also on the size of the system. The system is known to exhibit a condensation transition as well as ergodicity breaking and metastability in the thermodynamic limit. Results on equivalence of ensembles and metastability are characterised in terms of large deviation techniques. A discussion of the dynamics of the condensate is given in light of these results.
