Investigation of low temperature quantum crossover in Josephson junctions
arXiv:1706.03709 · doi:10.1063/1.4986757
Abstract
The evidence for macroscopic quantum tunneling (MQT) in Josephson junctions at low temperatures has been reassessed. Swept bias escape distributions have been modeled with an algorithm-based simulation and the results compared with data from representative published experiments. Signatures expected of a crossover to MQT are not found in the analyzed data.
