Monte Carlo study of pseudo-gap temperature [formula omitted] within JJA model

Abstract

We study pseudo-gap temperature T∗ of high-Tc superconductors by a Monte Carlo simulation of anisotropic 3D Josephson junction array (JJA) model based on the Ginzburg–Landau theory. We investigate T∗ both in the cases of zero external current and finite external current I in the JJA. It is found that, the external current I depresses only a little the pseudo-gap temperature T∗, while the superconducting critical temperature Tc is much affected by I.
