Nonlinearity induced destruction of resonant tunneling in the Wannier-Stark problem
arXiv:cond-mat/0506357 · doi:10.1103/PhysRevA.72.063610
Abstract
We present detailed numerical results on the dynamics of a Bose-Einstein condensate in a tilted periodic optical lattice over many Bloch periods. We show that an increasing atom-atom interaction systematically affects coherent tunneling, and eventually destroys the resonant tunneling peaks.
