Determination of Relaxation Time of a Josephson Tunnel Junction
Wen Xue-Da, Yang Yu · Chinese Physics Letters · 2008
We propose a non-stationary method to measure the energy relaxation time of Josephson tunnel junctions from microwave enhanced escape phenomena. Compared with the previous methods, our method possesses simple and accurate features. Moreover, having determined the energy relaxation time, we can further obtain the coupling strength between the microwave source and the junction by changing the microwave power.
