Wimberger, Sandro and Schlagheck, Peter and Mannella, Riccardo (2006) Tunnelling rates for the nonlinear Wannier-Stark problem. Journal of Physics B 39, p. 729.
We present a method to numerically compute accurate tunnelling rates for a Bose-Einstein condensate which is described by the nonlinear Gross-Pitaevskii equation. Our method is based on a sophisticated real-time integration of the complex-scaled Gross-Pitaevskii equation, and it is capable of finding the stationary eigenvalues for the Wannier-Stark problem. We show that even weak nonlinearities ...
