1304.4663 (Kevin Roberts et al.)

Numerical study of the stability regions for half-quantum vortices in
superconducting Sr2RuO4

Kevin Roberts, Raffi Budakian, Michael Stone
We numerically solve the coupled Landau-Ginzburg-Maxwell equations for a model of a spin triplet px + ipy 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.
