"BCS Theory of Anisotropic Fermi Superfluids"
Abstract
An interesting generalization of the original work of BCS is to Fermi superfluids in which the pairing is in a state of nonzero orbital angular momentum and/or nonzero spin. I discuss the application of such a description to the superfluid phases of liquid 3-He and to the cuprate superconductors, emphasizing both the similarities and the differences with the original s-wave theory.
