ABSTRACT

One of the main results of the last chapter was the hysteretic shape of the dc I–V curve of a Josephson junction with low damping (high capacitance, β ≫ 1). As a result of this shape, even a gradual change of the current I can lead to rapid transitions from the S branch of the I–V curve to the R branch and vice versa (Figure 4.1). In this chapter we will discuss the dynamics of these S → R switchings and R → S switching as well as that of transients in the junctions with high damping.
