The influence of ultra-fast laser pulses on electron transfer in molecular wires studied by a non-Markovian density matrix approach
Sven Welack, Michael Schreiber, Ulrich Kleinekathoefer
New features of molecular wires can be observed when they are irradiated by laser fields. These effects can be achieved by periodically oscillating fields but also by short laser p…
Multiscaling, Ergodicity and Localization in Quasiperiodic Chains
V. Z. Cerovski, M. Schreiber, U. Grimm
We report results of numerical simulations of wave-packet dynamics in a class of chains consisting of two types of weakly coupled clusters arranged in a quasiperiodic sequence. Pro…
Spectral and Diffusive Properties of Silver-Mean Quasicrystals in 1,2, and 3 Dimensions
V. Z. Cerovski, M. Schreiber, U. Grimm
Spectral properties and anomalous diffusion in the silver-mean (octonacci) quasicrystals in d=1,2,3 are investigated using numerical simulations of the return probability C(t) and…
Effects of Scale-Free Disorder on the Anderson Metal-Insulator Transition
Macleans L. Ndawana, Rudolf A. Roemer, Michael Schreiber
We investigate the three-dimensional Anderson model of localization via a modified transfer-matrix method in the presence of scale-free diagonal disorder characterized by a disorde…
Anisotropic Quantum Hall Matrix Model
Ahmed Jellal, Rudolf A. Roemer, Michael Schreiber
We consider the anisotropic effect in the quantum Hall systems by applying a confining potential that is not of parabolic type. This can be done by extending Susskind--Polychronako…
Stochastic unraveling of Redfield master equations and its application to electron transfer problems
Ivan Kondov, Ulrich Kleinekathoefer, Michael Schreiber
A method for stochastic unraveling of general time-local quantum master equations (QMEs) is proposed. The present kind of jump algorithm allows a numerically efficient treatment of…
