Abstract

We numerically solve the coupled Landau-Ginzburg-Maxwell equations for a model of a spin triplet p_x+ip_y superconductor in which whole or half-quanta of flux thread through a hole. We recover the pattern of stable and unstable regions for the half-flux quanta observed in a recent experiment. We also examine a scenario with bent, Abrikosov integer vortices and find it implausible for the thin, mesoscopic ring geometry considered.
