"Fermionic atoms in optical lattices: Mott transition
and metastable superconductivity"
Cold fermionic atoms in optical
lattices offer not only the possibility to simulate fundamental effects of
material physics but also to explore new physical phenomena. The response of a
strongly interacting atomar cloud on an adiabatic
change of the confining potential can be used to detect the Mott transition. We
compare dynamical mean field calculations for the Hubbard model with recent
measurements by the Bloch group
