Optimization by thermal cycling
A. Mobius, A. Neklioudov, A. Diaz-Sanchez +3
An optimization algorithm is presented which consists of cyclically heating and quenching by Metropolis and local search procedures, respectively. It works particularly well when i…
Energy spectra and eigenstates of quasiperiodic tight-binding Hamiltonians
Uwe Grimm, Michael Schreiber
Analytic and numerical results for quasiperiodic tight-binding models are reviewed, with emphasis on two and three-dimensional models which so far are beyond a mathematically rigor…
Non-ergodic effects in the Coulomb glass: specific heat
A. Díaz-Sánchez, A. Möbius, M. Ortuño +2
We present a numerical method for the investigation of non-ergodic effects in the Coulomb glass. For that, an almost complete set of low-energy many-particle states is obtained by…
Critical properties of the metal-insulator transition in anisotropic systems
Frank Milde, Rudolf A. Römer, Michael Schreiber +1
We study the three-dimensional Anderson model of localization with anisotropic hopping, i.e., weakly coupled chains and weakly coupled planes. In our extensive numerical study we i…
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…
Does a magnetic field modify the critical behaviour at the metal-insulator transition in 3-dimensional disordered systems?
E. Hofstetter, M. Schreiber
The critical behaviour of 3-dimensional disordered systems with magnetic field is investigated by analyzing the spectral fluctuations of the energy spectrum. We show that in the th…
