A critical look at quantum diffusion and some of its interesting aspects

Abstract

A fresh and critical look has been given to the long-time behaviour of the quantum diffusion problem and a marginally more accurate solution has been obtained as compared to the one reported in the recent literature. Attempt has also been made to bring out a few interesting generic features of this problem which may have important bearing on real systems in the quantum domain. © 2007 EDP Sciences/Società Italiana di Fisica/Springer-Verlag.
