Vortex dynamics in the two-dimensional BCS-BEC crossover
Abstract
The crossover between the limiting ground states of fermionic systems, the so called BCS-BEC crossover, is of interest to superconductor and ultracold atomic gases communities. The authors study the dynamics of superconducting vortices in the crossover regime via the Hall response in a 2D superconductor LixZrNCl.
