Abstract

Time-dependent Ginsburg-Landau theory is combined with Langevin, Fokker-Planck and nonstationary Schrödinger equation techniques to model impact of thermal noise in kinetics of ferroelectric polarization. A real space/real time method based on Cayley's form and Suzuki's decomposition is implemented for numerically simulating both relaxation of polarization in a static potential and dynamic hysteresis in arbitrary time dependent potential. Results are addressed to high field response and long time dynamics in ferroelectrics.
