Monte Carlo study of pseudo-gap temperature T∗ within JJA model

Abstract We study pseudo-gap temperature T ∗ of high- T c 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 T c is much affected by I .
