INFLUENCE OF THERMAL FLUCTUATIONS ON CRITICAL CURRENT OF JOSEPHSON JUNCTION WITH UNCONVENTIONAL CURRENT-PHASE RELATION

In this study we carried out the analysis of the thermal fluctuations of Josephson junction (JJ) with unconventional current-phase relation (CPR). It was obtained expression for the critical current fluctuations in case of linear growing of current via junction in limits of low sampling rate. It is shown that, the dynamical properties of JJ with unconventional CPR is determined by the renormalized critical current of JJ.
