Switching current distributions in Josephson junctions at very low temperatures
2014
Abstract
Swept bias experiments carried out on Josephson junctions yield the distributions of the probabilities of early switching from the zero-voltage state. Kramers' theory of the thermally activated escape from a one-dimensional potential is well known to fall short of explaining such experiments when the junctions are at millikelvin temperatures. We propose a simple revision of the theory which is shown to give extremely good agreement with experimental data. Copyright (C) EPLA, 2014File in questo prodotto:
