Interface Roughening in Two Dimensions
JOURNAL OF STATISTICAL PHYSICS(2021)
摘要
Roughening of interfaces implies the divergence of the interface width w with the system size L . For two-dimensional systems the divergence of w^2 is linear in L . In the framework of a detailed capillary wave approximation and of statistical field theory we derive an expression for the asymptotic behaviour of w^2 , which differs from results in the literature. It is confirmed by Monte Carlo simulations.
