Spectral properties and phase diagram of correlated lattice bosons in an optical cavity within the B-DMFT
arXiv:1607.00671 · doi:10.1103/PhysRevB.95.115105
Abstract
We use the Bose-Hubbard model with an effective infinite-range interaction to describe the correlated lattice bosons in an optical cavity. We study both static and spectral properties of such system within the bosonic dynamical mean-field theory (B-DMFT), which is the state of the art method for strongly correlated bosonic systems. Both similarities and differences are found and discussed between our results and these obtained within different theoretical methods and experiment.
