This study presents the analysis of the structure of fermionic vortices with spin-polarized cores, from a weak coupling limit to the unitary regime. The mechanism for the generation of reversed circulation in the vortex core induced by an excess of majority spin particles is shown. A classification of polarized vortices based on the number of Fermi circles where the minigap vanishes is introduced. The study also analyzes the effective mass of quasiparticles along the vortex core and discusses its role in the propagation of spin-polarization along the vortex line.
We present the analysis of the structure of fermionic vortices with the spin-polarized core from a weak coupling limit to the unitary regime. We show the mechanism for the generation of the reversed circulation in the vortex core induced by an excess of majority spin particles. We introduce the classification of the polarized vortices based on the number of Fermi circles where the minigap vanishes. This provides a unique description of the vortex as one cannot smoothly map wave functions into one another corresponding to vortices differing by the number of Fermi circles. The effective mass of quasiparticles along the vortex core is analyzed and its role in the propagation of spin-polarization along the vortex line is discussed.
