Localization of the mean-field superconducting order parameter on random wire networks

Abstract
Studies of the magnetic-field dependence of the mean-field transition temperature Tc(H) of square superconducting wire networks from which bonds have been removed randomly reveal a washing out of the cusps in the phase boundary curve with decreasing bond occupation probability p. These results are consistent with computations implying localization of the mean-field superconducting order parameter.
