Description:
Author(s): Anna Golubeva, Andrii Sotnikov, and Walter Hofstetter We study the effects of anisotropic hopping amplitudes on quantum phases of ultracold fermions in optical lattices described by the repulsive Fermi-Hubbard model. In particular, using dynamical mean-field theory (DMFT) we investigate the dimensional crossover between the isotropic square and the iso… [Phys. Rev. A 92, 043623] Published Mon Oct 26, 2015
