Description:

Liquid helium-3-A is the first laboratory system confidently believed to undergo Cooper pairing in a non-s-wave state,and it has been widely used as an analog for certain metallic systems such as strontium ruthenate,with both falling into the class of "p+ip" Fermi superfluids.One of the most fascinating predictions concerning this class of systems is that they may be able to sustain exotic quasi-fermionic excitations such as Majorana fermions,and that these may then be used to implement topological quantum computation.I review the current state of play regarding the p+ip Fermi superfluids,and call attention to some questions about them which I believe are unresolved.
