PARITY EFFECT IN A SMALL SUPERCONDUCTING PARTICLE
/ Authors
/ Abstract
Matveev and Larkin calculated the parity effect on the ground-state energy of a small superconducting particle in the regimes where the mean level spacing $\ensuremath{\delta}$ is either large or small compared to the bulk gap $\ensuremath{\Delta}.$ We perform a numerical calculation which extends their results to intermediate values of $\ensuremath{\delta}/\ensuremath{\Delta}.$
