Abstract

Abstract : For more than 20 years, experimenters have used the resistively- and- capacitively-shunted-junction (RCSJ) model to predict the dynamics of Josephson junctions. As the sample area decreases, two effects ignored in the model become relevant: First, the low impedance of the leads at high frequency (roughly 100 ohms compared to the dc impedance of 1 giga ohm, and second, quantum fluctuations of phi, the order parameter phase difference between the junction electrodes. We have observed dramatic evidence of the importance of both these effects. Keywords: Josephson junctions; Tunnel junctions; Superconductors.
