Frequency dependent transport in the integer quantum Hall effect
A. Bäker, L. Schweitzer
The frequency dependent transport is investigated for a two-dimensional disordered system under QHE conditions. The real and imaginary parts of the conductivity are calculated nume…
Localization of electrons in two-dimensional spatially-correlated random magnetic fields
H. Potempa, L. Schweitzer
The localization properties of electrons moving in a plane perpendicular to a spatially-correlated static magnetic field of random amplitude and vanishing mean are investigated. We…
Frequency dependent conductivity in the integer quantum Hall effect
A. Bäker, L. Schweitzer
Frequency dependent electronic transport is investigated for a two-dimensional disordered system in the presence of a strong perpendicular static magnetic field. The ac-conductivit…
Critical dynamics and multifractal exponents at the Anderson transition in 3d disordered systems
Tobias Brandes, Bodo Huckestein, Ludwig Schweitzer
We investigate the dynamics of electrons in the vicinity of the Anderson transition in dimensions. Using the exact eigenstates from a numerical diagonalization, a number of q…
