Breaking of SU(4) symmetry and interplay between strongly correlated phases in the Hubbard model
A. Golubeva, A. Sotnikov, A. Cichy +2
We study the thermodynamic properties of four-component fermionic mixtures described by the Hubbard model using the dynamical mean-field-theory approach. Special attention is given…

Effects of anisotropy in simple lattice geometries on many-body properties of ultracold fermions in optical lattices
Anna Golubeva, Andrii Sotnikov, 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, us…
