Critical parameters for the disorder-induced metal-insulator transition in FCC and BCC lattices
Andrzej Eilmes, Andrea M. Fischer, Rudolf A. Römer
We use a transfer-matrix method to study the disorder-induced metal-insulator transition. We take isotropic nearest- neighbor hopping and an onsite potential with uniformly distrib…
Exponents of the localization length in the 2D Anderson model with off-diagonal disorder
Andrzej Eilmes, Rudolf A. Roemer
We study Anderson localization in two-dimensional systems with purely off-diagonal disorder. Localization lengths are computed by the transfer-matrix method and their finite-size a…
Localization properties of two interacting particles in a quasi-periodic potential with a metal-insulator transition
Andrzej Eilmes, Rudolf A. Roemer, Michael Schreiber
We study the influence of many-particle interactions on a metal-insulator transition. We consider the two-interacting-particle problem for onsite interacting particles on a one-dim…
Exponents of the localization lengths in the bipartite Anderson model with off-diagonal disorder
Andrzej Eilmes, Rudolf A. Roemer, Michael Schreiber
We investigate the scaling properties of the two-dimensional (2D) Anderson model of localization with purely off-diagonal disorder (random hopping). In particular, we show that for…
Two interacting particles at the metal-insulator transition
Andrzej Eilmes, Uwe Grimm, Rudolf A. Roemer +1
To investigate the influence of electronic interaction on the metal-insulator transition (MIT), we consider the Aubry-André (or Harper) model which describes a quasiperiodic one-di…
The two-dimensional Anderson model of localization with random hopping
Andrzej Eilmes, Rudolf A. Roemer, Michael Schreiber
We examine the localization properties of the 2D Anderson Hamiltonian with off-diagonal disorder. Investigating the behavior of the participation numbers of eigenstates as well as…
