Excitation spectrum of Mott shells in optical lattices
Dirk-Sören Lühmann, Kai Bongs, Daniela Pfannkuche
We theoretically study the excitation spectrum of confined macroscopic optical lattices in the Mott-insulating limit. For large systems, a fast numerical method is proposed to calc…
Role of interactions in 87Rb-40K Bose-Fermi mixtures in a 3d optical lattice
Th. Best, S. Will, U. Schneider +4
We investigate the effect of interspecies interaction on a degenerate mixture of bosonic 87Rb and fermionic 40K atoms in a three-dimensional optical lattice potential. Using a Fesh…
Self-Trapping of Bosons and Fermions in Optical Lattices
Dirk-Sören Lühmann, Kai Bongs, Klaus Sengstock +1
We theoretically investigate the enhanced localization of bosonic atoms by fermionic atoms in three-dimensional optical lattices and find a self-trapping of the bosons for attracti…
