I will talk about quantum phases of fermions in optical lattices.
For repulsive interactions what are the entropy constraints to see the anti-ferromagnetic phase?
What is the role of the trap?
For attractive interactions and unequal populations of up and down fermions what are the signatures of the
I will talk about new unpublished results for both topics.
