We have discussed bosonic and fermionic superfluids. The underlying mechanisms were, on the one hand, Bose-Einstein condensation (BEC) and, on the other hand, Cooper pairing according to Bardeen-Cooper-Schrieffer (BCS) theory. We have also mentioned that fermionic superfluidity is also a form of BEC because a Cooper pair can, in some sense, be considered as a boson. However, this picture has of course to be taken with some care. When we discussed Cooper pairing, we were working in the weak-coupling limit.
