Kramers and non-Kramers Phase Transitions in Many-Particle Systems with Dynamical Constraint

Abstract

We study a Fokker-Planck equation with double-well potential that is nonlocally driven by a dynamical constraint and involves two small parameters. Relying on formal asymptotics we identify several parameter regimes and derive reduced dynamical models for different types of phase transitions.
