Dynamics of interacting atoms in driven tilted optical lattices
Andrey R. Kolovsky, Hans Jürgen Korsch
The dynamics of cold Bose atoms in driven tilted optical lattices is analyzed focusing on destruction of Wannier-Stark localization and the phenomenon of band collapse. It is argue…
Classical limit of non-Hermitian quantum dynamics - a generalised canonical structure
Eva-Maria Graefe, Michael Hoening, Hans Juergen Korsch
We investigate the classical limit of non-Hermitian quantum dynamics arising from a coherent state approximation, and show that the resulting classical phase space dynamics can be…
Multi-barrier resonant tunneling for the one-dimensional nonlinear Schrödinger Equation
K Rapedius, H J Korsch
For the stationary one-dimensional nonlinear Schrödinger equation (or Gross-Pitaevskii equation) nonlinear resonant transmission through a finite number of equidistant identical ba…
Bose-Einstein condensates on tilted lattices: coherent, chaotic and subdiffusive dynamics
Andrey R. Kolovsky, Edgar A. Gómez, Hans Jürgen Korsch
The dynamics of a (quasi)one-dimensional interacting atomic Bose-Einstein condensate in a tilted optical lattice is studied in a discrete mean-field approximation, i.e., in terms o…
Bloch oscillations of Bose-Einstein condensates: Quantum counterpart of dynamical instability
Andrey R. Kolovsky, Hans Jürgen Korsch, Eva-Maria Graefe
We study the Bloch dynamics of a quasi one-dimensional Bose-Einstein condensate of cold atoms in a tilted optical lattice modeled by a Hamiltonian of Bose-Hubbard type: The corresp…
