Vortex States in Fermi-Bose Mixtures

Abstract

We consider a vortex state in a confined mixture of bosons and fermions in the quantal degeneracy regime with attractive boson–fermion interactions. Within a mean-field description, we obtain the equilibrium configurations and investigate the phase-stability diagram of the K–Rb mixture assuming that the Bose–Einstein condensate sustains a quantized vortex line.
