Persistent Flow in Fermionic Superfluid Rings

We will report on our efforts to create persistent currents and Josephson junctions in a ring of dilute fermionic superfluid, which requires a somewhat different technical approach than previous experiments with bosonic superfluids. Our goal is to test predictions of quantum many-body theory for superflows in this setting. After validating these methods in the well-understood BEC-BCS regime, we will apply them to studying transport phenomena in unconvenional fermionic superfluids and other exotic quantum phases of matter.
