A new type of super fluid

I discuss the superfluid ground state and excitations of spin-1/2 fermions in the unitary limit. The unitary limit describes an interesting bit of universal physics that occurs when the range of the attractive force between particles is negligible and the strength of the interaction is tuned to produce a zero-energy resonance. I discuss relevance to dilute neutron matter, cold atomic Fermi gas experiments, and new theoretical results.
