Josephson-Current Fluctuations in Dirty SNS Junctions
スポンサーリンク
概要
- 論文の詳細を見る
Sample-to-sample fluctuations of the Josephson current in superconductor-dirty normal metal-superconductor junctions are studied numerically using a tight-binding model. Particular attention is given to the cases where the correlation energy of the normal metal is smaller than the superconducting pair potential. It is found that the amplitude of the critical-current fluctuation is of order of the correlation energy. This result is in qualitative agreement with the theory of Al'tshuler and Spivak.
