    Abstract

    We study I-V characteristics of periodic square Nb wire networks as a function of temperature in a transverse magnetic field, with a focus on three fillings 2/5, 1/2, and 0.618 that represent very different levels of incommensurability. For all three fillings, a scaling behavior of I-V characteristics is found, suggesting a finite temperature continuous superconducting phase transition. The low-temperature I-V characteristics are found to have an exponential form, indicative of the domain-wall excitations.
