Tails of the Density of States in a Random Magnetic Field
Riccardo Mazzarello, Stefan Kettemann, Bernhard Kramer
We study the tails of the density of states of fermions subject to a random magnetic field with non-zero mean with the Optimum Fluctuation Method (OFM). Closer to the centres of th…

Rashba effect and magnetic field in quantum wires
Stefan Debald, Bernhard Kramer
We investigate the influence of a perpendicular magnetic field on the spectral and spin properties of a ballistic quasi-one-dimensional electron system with Rashba effect. The magn…

Random Network Models and Quantum Phase Transitions in Two Dimensions
B. Kramer, T. Ohtsuki, S. Kettemann
An overview of the random network model invented by Chalker and Coddington, and its generalizations, is provided. After a short introduction into the physics of the Integer Quantum…
