Beyond mean-field dynamics in open Bose-Hubbard chains
D. Witthaut, F. Trimborn, H. Hennig +3
We investigate the effects of phase noise and particle loss on the dynamics of a Bose-Einstein condensate in an optical lattice. Starting from the many-body master equation, we dis…
Taming chaos by impurities in two-dimensional oscillator arrays
M. Weiss, Tsampikos Kottos, T. Geisel
The effect of impurities in a two-dimensional lattice of coupled nonlinear chaotic oscillators and their ability to control the dynamical behavior of the system are studied. We sho…
Quantum mechanical relaxation of open quasiperiodic systems
A. Ossipov, M. Weiss, Tsampikos Kottos +1
We study the time evolution of the survival probability in open one-dimensional quasiperiodic tight-binding samples of size , at critical conditions. We show that it deca…
Bloch Electrons in a Magnetic Field - Why Does Chaos Send Electrons the Hard Way?
R. Ketzmerick, K. Kruse, D. Springsguth +1
We find that a 2D periodic potential with different modulation amplitudes in x- and y-direction and a perpendicular magnetic field may lead to a transition to electron transport al…
Nonlinear Dynamics of Composite Fermions in Nanostructures
R. Fleischmann, T. Geisel, C. Holzknecht +1
We outline a theory describing the quasi-classical dynamics of composite fermions in the fractional quantum Hall regime in the potentials of arbitrary nanostructures. By an appropr…
