The physical properties of an ensemble of disordered ultra-small superconducting grains are analyzed by means of a simple Hamiltonian. We find that both the thermodynamical observables and the interplay between the pairing and exchange interactions display universal features.

Abstract
The physical properties of an ensemble of disordered ultra-small superconducting grains are analyzed by means of a simple Hamiltonian. We find that both the thermodynamical observables and the interplay between the pairing and exchange interactions display universal features.File in questo prodotto:
