Scaling Laws for Fluxon Formation in Annular Josephson Tunnel Junctions | | R.Monaco

16 Dec 2002 | | Subject: | Superconductivity | cond-mat.supr-con | | 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 $sigma $ for the production of fluxons in annular symmetric Josephson Tunnel Junctions. The predicted exponent is $% sigma =0.25$, and we find $sigma =0.27pm 0.05$. Further, there is agreement with the ZK prediction for the overall normalisation. | | Source: | arXiv, cond-mat/0301294 | | Services: | Forum | Review | PDF | Favorites | |
