Anisotropic superfluidity

Chris Ticknor

A quintessential feature of superfluidity is its ability to support dissipationless flow. The break down of superfluidity occurs when an obstacle moves too fast through the gas and it excites the gas resulting in dissipation. Superfluids have been isotropic, but we present theory that shows ultracold dipolar gases are an anisotropic superfluid. This means that the fluid has distinct critical velocities depending on the direction one moves in the fluid. We discuss this intriguing system and its properties.
