Few Remarks About Small Capacitance Josephson Junctions
For most purposes, the current voltage characteristic (I/V) of junctions with superconducting electrodes can be satisfactorily described by means of the so called Resistive Shunted Junction model (RSJ), just in terms of the dynamics of the classical variable φ. This is the difference in the phase of the order parameter between the two superconductors. Dissipation is phenomenologically included as an ohmic term in the equation of motion for φ, by means of a suitably defined resistance R.
