Abstract

Recently, studies involving coherent transient phenomena in Josephson devices have been discussed from a quantum optical perspective [1,2]. The motivation for these investigations has been the close analogy between two-level quantum optical systems and Josephson devices [3]. In particular, the angular momentum formulation of an n-atom system according to Dicke [4] has a close analogy to the corresponding problem of n-Cooper pairs interacting with the radiation field in a Josephson tunnel junction. In this article, we briefly review the fundamental concepts of superconductivity and superconducting tunnel junctions, and emphasize the relation between Josephson junctions and superradiant physics. We then sketch the analysis as applied to a tunnel junction undergoing dynamical transients first from a quantum optical and then from the common phenomenological point of view. We find that the present results differ from those obtained in the usual phenomenological fashion.

    Strictly speaking Vo as it appears in this paper is the measured dc voltage. The electrostatic voltage will differ slightly from the measured voltage as discussed in detail in Ref. 13. This difference is of secondary importance to our main arguments about the variable 0. Consequently, we will often not distinguish between these two voltages.Google Scholar
