Interactions and localization: two interacting particles approach
D. L. Shepelyansky
Abstract
It is shown that two repulsing / attracting particles in a random potential can propagate coherently on a distance much larger than one-particle localization length without interaction. In dimension d this leads to delocalization of pairs formed by two repulsing / attracting particles. The results of numerical simulations allow to understand some specific features of this effect.
