Spontaneous Vortex Production in Driven Condensates with Narrow Feshbach Resonances

TL;DR

This paper investigates the spontaneous formation of vortices in cold Fermi atom condensates with narrow Feshbach resonances during rapid magnetic tuning from BEC to BCS regimes, suggesting experimental feasibility.

Contribution

It proposes a novel mechanism for vortex creation in Fermi condensates driven by rapid magnetic tuning across a narrow Feshbach resonance.

Findings

Vortices can form spontaneously at zero temperature.

Rapid magnetic tuning can induce vortex production.

Experimental techniques may realize this phenomenon.

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.
