We study the effects of the mesoscopic fluctuations on the interplay between the exchange and pairing interactions in a collection of monodispersed ultrasmall metallic dots when the average level spacing 6 is larger than the BCS pairing energy Delta. We find a universal and parity-dependent behavior of the ground state spin probabilities.

Abstract
We study the effects of the mesoscopic fluctuations on the interplay between the exchange and pairing interactions in a collection of monodispersed ultrasmall metallic dots when the average level spacing 6 is larger than the BCS pairing energy Delta. We find a universal and parity-dependent behavior of the ground state spin probabilities.File in questo prodotto:
