Optimal Allocation of External Fields for Nucleation of Ising Model on Modular Networks
摘要
Abstract
This paper discusses the nucleation in a first-order phase transition on a network with two modules.By applying two distinct external fields to each module , the effect of the diversity in external fields on nucleation rate is investigated under the constraint that the average external field is unchanged.By mean-field theory and umbrella sampling, we find that there exists an optimal diversity for which the nucleation rate is maximal .关键词
