Stochastic Resonance in a Bistable Squid Loop
Abstract
Stochastic Resonance (SR) is the name given to a statistical nonlinear phenomenon whereby a weak or subthreshold coherent function can be amplified by random forces, or nose, within the system. It was first advanced in the early 1980's as a possible explanation for the observed periodicities in the recurrences of the Earth's Ice Ages. The first publication of a modern theory led to an experiment and a flurry of further theoretical activity, an international conference and a review. In this paper, we describe a demonstration experiment wherein SR is exhibited in a superconducting quantum interference device (SQUID). Here SR is viewed as a noisy information transmission process. It is entirely appropriate, therefore, to look for this dynamic in a widely used sensitive detector; in this example, a detector of weak magnetic fields. Using a modem, miniature, thin film SQUID, we hope this demonstration will stimulate further research and development of SR in applied superconductivity
