New cooling techniques combined with Feshbach resonances
to tune the coupling strength between atoms, has enabled
the creation of fermionic superfluids in ultra-cold atomic gases.
I will give an overview of this rapidly developing field
of ultra-cold Fermi gases and towards the end of my talk I will
discuss the physics in optical lattices in greater detail.
In particular, I will outline the expected phase-diagram
for two-component systems with population mismatch.
