Time Domain Analysis of Dynamical Switching in a Josephson Junction
2004 (English)Manuscript (preprint) (Other academic)
We have studied the switching behaviour of a small capacitance Josephson junction both in experiment,and by numerical simulation of a model circuit. The switching is a complex process involvingthe transition between two dynamical states of the non-linear circuit, arising from a frequency dependentdamping of the Josephson junction. We show how a specific type of bias pulse-and-hold,can result in a fast detection of switching, even when the measurement bandwidth of the junctionvoltage is severely limited, and/or the level of the switching current is rather low.
