Dynamical Scaling Properties of Electrons in Quantum Systems with Multifractal Eigenstates
Jianxin Zhong, Zhenyu Zhang, Michael Schreiber +2
We study the intricate relationships between the dynamical scaling properties of electron wave packets and the multifractality of the eigenstates in quantum systems. Numerical simu…
Metal-insulator transition in anisotropic systems
F. Milde, R. A. Roemer, M. Schreiber
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…
Critical behavior of the thermoelectric transport properties in amorphous systems near the metal-insulator transition
C. Villagonzalo, R. A. Roemer, M. Schreiber +1
The scaling behavior of the thermoelectric transport properties in disordered systems is studied in the energy region near the metal-insulator transition. Using an energy-dependent…
Trace and antitrace maps for aperiodic sequences, their extensions and applications
Xiaoguang Wang, Uwe Grimm, Michael Schreiber
We study aperiodic systems based on substitution rules by means of a transfer-matrix approach. In addition to the well-known trace map, we investigate the so-called `antitrace' map…
Photo-induced intermolecular charge transfer in porphyrin complexes
Michael Schreiber, Dmitry Kilin, Ulrich Kleinekathoefer
Optical excitation of the sequential supermolecule H_2P-ZnP-Q induces an electron transfer from the free-base porphyrin (H_2P) to the quinone (Q) via the zinc porphyrin (ZnP). This…
Cumulant expansion method in the density matrix approach to wave packet dynamics in molecular systems
M. Schreiber, D. Kilin
A non-Markovian master equation for a molecule interacting with a heat bath is obtained using the cumulant expansion method. The equation is applied to the problem of molecular wav…
