The Dissipative Bose-Hubbard Model. Methods and Examples
G. Kordas, D. Witthaut, P. Buonsante +4
Open many-body quantum systems have attracted renewed interest in the context of quantum information science and quantum transport with biological clusters and ultracold atomic gas…
Manifold approach for a many-body Wannier-Stark system: localization and chaos in energy space
C. A. Parra-Murillo, S. Wimberger
We study the resonant tunneling effect in a many-body Wannier-Stark system, realized by ultracold bosonic atoms in an optical lattice subjected to an external Stark force. The prop…
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…
Time-resolved measurement of Landau--Zener tunneling in different bases
G. Tayebirad, A. Zenesini, D. Ciampini +5
A comprehensive study of the tunneling dynamics of a Bose--Einstein condensate in a tilted periodic potential is presented. We report numerical and experimental results on time-res…
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…
