Switching as an exit problem

Previously, it has been shown that Preisach type models driven by stochastic inputs can be employed to model aftereffect. In this model, the machinery of the "exit problem" is instrumental in computing the time evolutions of the expected value and the distributions of switching times. Here, for the first time, we present numerical simulation results of the aforementioned viscosity models and demonstrate that these models can be employed to compute switching times and time evolutions of the expected value of magnetization.
