Abstract
Effects of electron-electron interaction for the quantum diffusion is inves tigated numerically in quasi one-dimensional systems (coupled chains) with a few particles. We have observed localization even with the interaction af ter sufficient time evolution. The localization length xi increases by the interactions in the weak coupling region. Also significant enhancement of t he localization length xi is observed by the increase of the chain numbers.
