Spontaneous Vortex Production in Driven Condensates with Narrow Feshbach Resonances

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.
