摘要：

Exact results are presented for the quantum diffusion of a tight-binding spinless many-fermion system in any dimension with site energies having a random white-noise frequency spectrum of arbitrary strength. In the limit of strong coupling to the noise, it is shown that the system reduces to the Chudley-Elliott jump-diffusion model. © 1979 The American Physical Society.
