Fingerprints of classical diffusion in open 2D mesoscopic systems in the metallic regime
A. Ossipov, Tsampikos Kottos, T. Geisel
We investigate the distribution of the resonance widths and Wigner delay times for scattering from two-dimensional systems in the diffusive regime. We…
Signatures of Prelocalized States in Classically Chaotic Systems
A. Ossipov, Tsampikos Kottos, T. Geisel
We investigate the statistics of eigenfunction intensities in dynamical systems with classical chaotic diffusion. Our results contradict some recent theoretical c…
Superballistic spreading of wave packets
L. Hufnagel, R. Ketzmerick, T. Kottos +1
We demonstrate for various systems that the variance of a wave packet , can show a {\it superballistic} increase with , for parametrically large time inte…
Statistics of resonances and of delay times in quasiperiodic Schr"odinger equations
F. Steinbach, A. Ossipov, Tsampikos Kottos +1
We study the statistical distributions of the resonance widths , and of delay times in one dimensional quasi-periodic tight-binding systems with one op…
Statistical properties of phases and delay times of the one-dimensional Anderson model with one open channel
A. Ossipov, Tsampikos Kottos, T. Geisel
We study the distribution of phases and of Wigner delay times for a one-dimensional Anderson model with one open channel. Our approach, based on classical Hamiltonian maps, allows…
Avoided Band Crossings: Tuning Metal-Insulator Transitions in Chaotic Systems
R. Ketzmerick, K. Kruse, T. Geisel
We show that avoided crossings of energy bands may give rise to a variety of phenomena such as transitions from metal to insulator and vice versa, changes in localization lengths,…
