Interaction-induced decoherence in non-Hermitian quantum walks of ultracold Bosons
K. Rapedius, H. J. Korsch
We study the influence of particle interaction on a quantum walk on a bipartite one-dimensional lattice with decay from every second site. The corresponding non-interacting (linear…

Nonlinear resonant tunneling of Bose-Einstein condensates in tilted optical lattices
K. Rapedius, C. Elsen, D. Witthaut +2
We study the tunneling decay of a Bose-Einstein condensate out of tilted optical lattices within the mean-field approximation. We introduce a novel method to calculate also excited…

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…
