摘要
Random walks in a disordered medium with a dipole-dipole transport are studied, ft is proved that the long-time asymptotic behavior is of a diffusion character and the diffusion coefficient is determined. The analysis is based on a new, efficient, numerical-modeling method employing direct calculation of the Fourier transform of the propagator and periodic continuation of the system without periodic continuation of the initial condition.
