Flux-noise spectra around the Kosterlitz-Thouless transition for two-dimensional superconductors

Superconductivity 2007-05-23 v2

Abstract

The flux-noise spectra around the Kosterlitz-Thouless transition are obtained from simulations of the two-dimensional resistively shunted junction model. In particular the dependence on the distance dd between the pick-up coil and the sample is investigated. The typical experimental situation corresponds to the large-dd limit and a simple relation valid in this limit between the complex impedance and the noise spectra is clarified. Features, which distinguish between the large- and small-dd limit, are identified and the possibility of observing these features in experiments is discussed.
