Opposite Chirality

Ground states are studied by solving a modified Ginzburg–Landau model for mesoscopic metallic superconducting rings. It is found that surface effect related spin-orbit (SO) interaction can generate an effective orbital magnetic field of opposite orientations for spin-up and spin-down electrons which leads to spin-polarized states with opposite chirality. The quantum phase transition between the spin-polarized states and spin singlet superconducting states can occur by applying an external magnetic field normal to the ring-plane.

Abstract We elaborate a theory of giant vortices [1] based on an asymptotic expansion in inverse powers of their winding number n. The theory is applied to the analysis of vortex solutions in the abelian Higgs (Ginzburg-Landau) model. Specific properties of the giant vortices for charged and neutral scalar fields as well as different integrable limits of the scalar self-coupling are discussed. Asymptotic results and the finite-n corrections to the vortex solutions are derived in analytic form and the convergence region of the expansion is determined.
