Phase Diagram and Spectral Function of the Two-Dimensional Disordered Bose-Hubbard Model: A Real-Space Dynamical Mean-Field Theory Analysis
Bastian Schindler, Renan da Silva Souza, Walter Hofstetter
We numerically investigate the two-dimensional Bose-Hubbard model with local onsite disorder, where the competition between disorder and short-range interactions leads to the emerg…

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…
