Vortex nucleation in deformed rotating cylinders

  • Alexander L. Fetter

Abstract

Superfluid states in a rotating elliptic cylinder are studied with semiclassical hydrodynamics. Two distinct approaches are used to obtain the critical angular velocity for the appearance of a vortex: (1) Equilibrium thermodynamics predicts that ω c1 increases monotonically with deformation at fixed cross-sectional area. (2) Predictions based on a critical slip speedv c at the walls depend on the detailed form ofv c ; the resulting ω c need not vary monotonically with deformation. The analogous situation in a rectangular cylinder is also discussed.
