Scaling Laws for Fluxon Formation in Annular Josephson Tunnel Junctions

Superconductivity 2007-05-23 v1

Abstract

It has been argued by Zurek and Kibble that the likelihood of producing defects in a continuous phase transition depends in a characteristic way on the quench rate. In this paper we discuss our experiment for measuring the Zurek-Kibble scaling exponent σ\sigma for the production of fluxons in annular symmetric Josephson Tunnel Junctions. The predicted exponent is % \sigma =0.25, and we find σ=0.27±0.05\sigma =0.27\pm 0.05. Further, there is agreement with the ZK prediction for the overall normalisation.
