Crossover from Anomalous to Normal Diffusion: Ising Model with Stochastic Resetting
Abstract
In this paper, we investigate the dynamics of the two-dimensional Ising model with stochastic resetting, utilizing a constant resetting rate procedure with zero-strength initial magnetization. Our results reveal the presence of a characteristic rate , where represents the system size and denotes the dynamical exponent. Below , both the equilibrium and dynamical properties remain unchanged. At the same time, for , the resetting process induces a transition in the probability distribution of the magnetization from a double-peak distribution to a three-peak distribution, ultimately culminating in a single-peak exponential decay. Besides, we also find that at the critical points, as increases, the diffusion of the magnetization changes from anomalous to normal, and the correlation time shifts from being dependent on to being -dependent only.
