Abstract

Effect of electromagnetic environment on the phase dynamics of small Josephson junctions is studied in connection with the dissipation in supercurrent branch observed by Iansiti et al. It is found that the dissipation is determined by the tunnel resistance of quasi-particles excited above the superconducting gap by the high-frequency quantum fluctuations in electromagnetic fields. This offers a possible explanation of the temperature-independent dissipation observed experimentally.
