Detection of Pair-Superfluidity for bosonic mixtures in optical lattices
arXiv:0912.4452 · doi:10.1103/PhysRevA.81.045604
Abstract
We consider a mixture of two bosonic species with tunable interspecies interaction in a periodic potential and discuss the advantages of low filling factors on the detection of the pair-superfluid phase. We show how the emergence of such a phase can be put dramatically into evidence by looking at the interference pictures and density correlations after expansion and by changing the interspecies interaction from attractive to repulsive.
