Expansion of a quantum gas released from an optical lattice
F. Gerbier, S. Trotzky, S. Foelling +9
We analyze the interference pattern produced by ultracold atoms released from an optical lattice. Such interference patterns are commonly interpreted as the momentum distributions…
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…
Quantum Many-Body Dynamics of Coupled Double-Well Superlattices
Peter Barmettler, Ana Maria Rey, Eugene Demler +3
We propose a method for controllable generation of non-local entangled pairs using spinor atoms loaded in an optical superlattice. Our scheme iteratively increases the distance bet…
