30 Mar 2005 | | Subject: | Superconductivity | cond-mat.supr-con | | Abstract: | Scaling behavior has been observed in the spontaneous production of fluxons in annular Josephson tunnel junctions as a function of the quench time, $ au _{Q}$, into the superconducting state. It has been found that, for $ au_{Q}$ larger than a threshold value of about 50ms, the probability, $f_{1}$, to trap a single defect during the N-S phase transition clearly follows an allometric dependence on $ au_{Q}$ with a critical exponent $sigma $ near 0.25, as predicted from the Kibble-Zurek mechanism. However, for $ au_{Q}$ below the threshold, $f_{1}$ flattens, suggesting that for very rapid quenches a new mechanism is at work; we suggest that thermal gradients may be responsible for the observed saturation in the small $ au_{Q}$ range. | | Source: | arXiv, cond-mat/0503707 | | Services: | Forum | Review | PDF | Favorites | |
