Berry phase mediated chiral p-wave superfluids of fermionic cold atoms

ORAL

Abstract

Two-dimensional px+ipy superfluids or superconductors offer a playground for studying intriguing physics such as quantum teleportation, non-Abelian statistics, and topological quantum computation. Creating such a superfluid in cold fermionic atom optical traps using p-wave Feshbach resonance is turning out to be challenging. Here we propose a method to create a px+ipy superfluid directly from an s-wave interaction making use of a topological Berry phase. Methods to generate the required topological Berry phase in cold atomic systems will be discussed.
