Scaling the localisation lengths for two interacting particles in one-dimensional random potentials
Using a numerical decimation method, we compute the localisation length λ2 for two onsite interacting particles (TIP) in a one-dimensional random potential. We show that an interaction U > 0 does lead to λ2(U) > λ2(0) for not too large U and test the validity of various proposed fit functions for λ2(U). Finite-size scaling allows us to obtain infinite sample size estimates ξ2(U) and we find tha...
متن کاملInteraction - dependent enhancement of the localisation length fortwo interacting particles in a one - dimensional random
We present calculations of the localisation length, 2 , for two interacting particles (TIP) in a one-dimensional random potential, presenting its dependence on disorder, interaction strength U and system size. 2 (U) is computed by a decimation method from the decay of the Green function along the diagonal of nite samples. Innnite sample size estimates 2 (U) are obtained by nite-size scaling. Fo...

متن کاملBreit - Wigner width for two interacting particles in one - dimensional random potential
For two interacting particles (TIP) in one-dimensional random potential the dependence of the Breit-Wigner width Γ, the local density of states and the TIP localiza-tion length on system parameters is determined analytically. The theoretical predictions for Γ are confirmed by numerical simulations.
متن کاملLocalization of two interacting particles in a one-dimensional random potential
We investigate the localization of two interacting particles in a one-dimensional random potential. Our definition of the two-particle localization length, j, is the same as that of von Oppen et al. @Phys. Rev. Lett. 76, 491 ~1996!#. j’s for chains of finite lengths are calculated numerically using the recursive Green’s function method for several values of the strength of the disorder, W , and...
