Off-resonant many-body quantum carpets in strongly tilted optical lattices
Manuel H. Muñoz-Arias, Javier Madroñero, Carlos A. Parra-Murillo
An unit filling Bose-Hubbard Hamilonian embedded in strong Stark field is studied in the off-resonant regime inhibiting single and many-particle first order tunneling resonances. W…
Chaotic level mixing in a two-band Bose-Hubbard model
C. A. Parra-Murillo, J. Madronero, S. Wimberger
We present a two-band Bose-Hubbard model which is shown to be minimal in the necessary coupling terms at resonant tunneling conditions. The dynamics of the many-body problem is stu…
Exact numerical methods for a many-body Wannier Stark system
Carlos A. Parra-Murillo, Javier Madroñero, Sandro Wimberger
We present exact methods for the numerical integration of the Wannier-Stark system in a many-body scenario including two Bloch bands. Our ab initio approaches allow for the treatme…
