INFLUENCE OF ORDER PARAMETER SYMMETRY ON CURRENT-PHASE DEPENDENCE IN SIS JUNCTIONS

Abstract

Equilibrium current states in tunnel superconducting junctions based on two-band superconductors have been studied. The study is based on quasiclassical equations for Green's functions written in the t-representation. The formula for the dependence of the current on the phase difference of the order parameters is obtained and the influence of the symmetry of the order parameters on the value of the superconducting current in the SIS contact is analyzed.
