Add to Calendar 4/25/2018 4:00 pm 4/25/2018 America/Chicago Physics Colloquium: Ralph O. Simmons Distinguished Lecture - "Liquid helium-3 and its metallic cousins: exotic pairing and exotic excitations" 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 "2D 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.
