Abstract

Thermal fluctuation for the time-dependent Ginzburg-Landau simulations is considered on the basis of the ensemble theory and the fluctuation-dissipation 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 coarse-grained volume and the curvature of the free-energy function at thermal equilibrium. The validity of the formula is verified by numerical simulation.
