Integer quantum Hall transition in the presence of a long-range-correlated quenched disorder
P. Cain, M. E. Raikh, R. A. Roemer +1
We theoretically study the effect of long-ranged inhomogeneities on the critical properties of the integer quantum Hall transition. For this purpose we employ the real-space renorm…
Off-diagonal disorder in the Anderson model of localization
P. Biswas, P. Cain, R. A. Roemer +1
We examine the localization properties of the Anderson Hamiltonian with additional off-diagonal disorder using the transfer-matrix method and finite-size scaling. We compute the lo…
Numerical results for two interacting particles in a random environment
R. A. Roemer, M. Leadbeater, M. Schreiber
Much evidence has been collected to date which shows that repulsive electron-electron interaction can lead to the formation of particle pairs in a one-dimensional random energy lan…
Universal level-spacing statistics in quasiperiodic tight-binding models
Uwe Grimm, Rudolf A. Roemer, Michael Schreiber +1
We study statistical properties of the energy spectra of two-dimensional quasiperiodic tight-binding models. The multifractal nature of the eigenstates of these models is corrobora…
Thermoelectric Transport Properties in Disordered Systems Near the Anderson Transition
C. Villagonzalo, R. A. Roemer, M. Schreiber
We study the thermoelectric transport properties in the three-dimensional Anderson model of localization near the metal-insulator transition [MIT]. In particular, we investigate th…
Level-Spacing Distributions of Planar Quasiperiodic Tight-Binding Models
J. X. Zhong, U. Grimm, R. A. Roemer +1
We study the statistical properties of energy spectra of two-dimensional quasiperiodic tight-binding models. We demonstrate that the nearest-neighbor level spacing distributions of…
