摘要：

In the Ginzburg-Landau (GL) theory of an unconventional superconductor, an applied magnetic field can induce superconductivity for T > T(c0), if the coefficients in the GL functional are in the appropriate range. We study the spatial structure of the ensuing superconducting state, using a simulated annealing method to find the configurations of the order parameter and vector potential which minimize the GL functional.
