Effect of Two-Body Interactions on Floquet topological phases
Arijit Dutta, Souradeep Roy Choudhury, Tao Qin +1
We study the circularly driven Falicov-Kimball model on a honeycomb lattice within real space Floquet dynamical mean field theory (DMFT). The noninteracting version of this model h…

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…
