No enhancement of the localization length for two interacting particles in a random potential

Description

We study two interacting particles in a random potential chain by means of the transfer matrix
method. The dependence of the two-particle localization length lampta_2 on disorder and interaction
strength is investigated. Our results demonstrate that the recently proposed enhancement of lampta_2 as
compared to the results for single particles is entirely due to the finite size of the systems considered.
This is shown for a Hubbard-like onsite interaction and also a long-range interaction.
