Abstract
Two-dimensional () 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 -wave Feshbach resonance is turning out to be challenging. Here we propose a method to create a superfluid directly from an -wave interaction making use of a topological Berry phase, which can be artificially generated. We discuss ways to detect the spontaneous Hall mass current, which acts as a diagnostic for the chiral -wave superfluid.
