Josephson tunneling as a probe of the vortex-glass state

Paul M. Goldbart, Efrat Shimshoni

Research output: Contribution to journalArticlepeer-review


Josephson tunneling between superconducting electrodes in the vortex-glass state is considered. The Josephson coupling energy and phase offset are stochastic, the typical value of the former scaling as the Edwards-Anderson order parameter, Larkin-Ovchinikov length, and square root of the junction area. The influence of magnetic flux through the junction is explored, and magneto-fingerprints, reminiscent of universal conductance fluctuations, are predicted. Properties of SQUIDs are also examined, and it is concluded that Josephson phenomena may provide a useful probe of the vortex-glass state.
