Interaction induced delocalization of two particles: large system size calculations and dependence on interaction strength
Abstract
The localization length L2 of two interacting particles in a one-dimensional disordered system is studied for very large system sizes by an efficient and accurate variant of the Green function method. The numerical results (at the band center) can be well described by the functional form L2=L1[0.5+c(U) L1] where L1 is the one-particle localization length and the coefficient
