Quantum Degenerate Gases in an All-Optical Toroidal Trap

POSTER

Abstract

Quantum degenerate gases confined in a toroidal potential show persistent currents, azimuthal sound waves, and other transport phenomena related to coherent, unrestricted flow around the waveguide. Sound waves and vortex states in a ring can be used to for accurate, absolute rotation sensing. We report on the status of our all-optical toroidal trap for Bose-condensed $^{87}$Rb. We discuss techniques to generate angular momentum and unusual spin structures as well as future prospects with spinor gases and quantum degenerate lithium.
