Mott insulators and correlated superfluids in ultracold Bose-Fermi mixtures
Mott insulators and correlated superfluids in ultracold Bose-Fermi mixtures
We study the effects of interaction between bosons and fermions in Bose-Fermi mixtures loaded in an optical lattice. We concentrate on the destruction of a bosonic Mott phase driven by repulsive interaction between bosons and fermions. Once the Mott phase is destroyed, the system enters a superfluid phase where the …
