Spectral properties and phase diagram of correlated lattice bosons in an optical cavity within the B-DMFT
Jaromir Panas, Anna Kauch, Krzysztof Byczuk
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 propert…
Numerical calculation of spectral functions of the Bose-Hubbard model using B-DMFT
Jaromir Panas, Anna Kauch, Jan Kuneš +2
We calculate the momentum dependent spectral function of the Bose-Hubbard model on a simple cubic lattice in three dimensions within the bosonic dynamical mean-field theory (B-DMFT…
Strong-coupling solution of the bosonic dynamical mean-field theory
Anna Kauch, Krzysztof Byczuk, Dieter Vollhardt
We derive an approximate analytical solution of the self-consistency equations of the bosonic dynamical mean-field theory (B-DMFT) in the strong-coupling limit. The approach is bas…
