Dear all,
Tomorrow in the lecture we will finish our discussion about the Mott insulator with a comment about
the appearance of spatial structures in the presence of an overall harmonic confinement. We will
then move to a two-component Fermi gas in an optical lattice, a system which has attracted a lot of
interest in recent years. We will discuss a little bit why.
In particular we will see that in this system there is also a Mott insulator, and that the Mott phase is
characterized by an antiferromagnetic spin coupling due to the so-called super-exchange processes. I
will discuss on the observation of super-exchange in experiments. If we have time I will start with the
discussion of other lattice systems with cold gases in the so-called hard-core regime.
See you tomorrow!
Luis
