Thermal fluctuation for the timedependent GinzburgLandau simulation
Abstract
Thermal fluctuation for the timedependent GinzburgLandau simulations is considered on the basis of the ensemble theory and the fluctuationdissipation relation. The treatment for evaluating the thermal fluctuation for a nonconserved system is proposed and the formula for the fluctuation is presented. The magnitude of the fluctuation depends on the coarsegrained volume and the curvature of the freeenergy function at thermal equilibrium. The validity of the formula is verified by numerical simulation.
