Spontaneous Vortex Production in Driven Condensates with Narrow Feshbach Resonances
arXiv:0908.4254 · doi:10.1103/PhysRevA.84.013623
Abstract
We explore the possibility that, at zero temperature, vortices can be created spontaneously in a condensate of cold Fermi atoms, whose scattering is controlled by a narrow Feshbach resonance, by rapid magnetic tuning from the BEC to BCS regime. This could be achievable with current experimental techniques.
