Vortex dynamics in a rapidly rotating BEC

ORAL

Abstract

Vortex dynamics play a central role in the physics of fractional quantum Hall materials and superconductors. We study interacting vortices in a rotating BEC under a novel geometric squeezing probe. As the angular momentum of the BEC increases, like-sign vortices cluster due to a hydrodynamic instability. Adding further angular momentum creates charge-flux quasiparticles of vortices attached to BEC clusters. Using high-resolution in situ imaging, we directly observe the quantized edge current associated to these quasiparticles.
