Paramagnetic phases of strongly correlated ultracold fermions coupled to an optical cavity
Renan da Silva Souza, Youjiang Xu, Walter Hofstetter
We numerically study a gas of two-component fermions coupled to a transversely pumped optical cavity and confined to a two-dimensional static square optical lattice. In the dispers…
Emergence of damped-localized excitations of the Mott state due to disorder
R. S. Souza, Axel Pelster, F. E. A. dos Santos
A key aspect of ultracold bosonic quantum gases in deep optical lattice potential wells is the realization of the strongly interacting Mott insulating phase. Many characteristics o…
Green's function approach to the Bose-Hubbard model with disorder
Renan da Silva Souza, Axel Pelster, Francisco E. A. dos Santos
We analyse the distinction between the three different ground states presented by a system of spinless bosons with short-range interactions submitted to a random potential using th…
