Strongly Interacting Fermions in Optical Lattices — •Valentin Kasper and Christof Wetterich — Institut für Theoretische Physik, Universität Heidelberg

We investigate the thermodynamic properties of strongly interacting fermionic atoms trapped in an optical lattice. The strong coupling physics at a Feshbach resonance requires that we consider effects of the full band structure going beyond the fermionic single-band Hubbard model. We extend previous mean field calculations using the Functional Renormalization Group. This way the phase diagram at zero temperature is established.
