✦ Synopsis

We consider the thermodynamics of the parity effect in a superconducting island. It is shown that the contribution of the order parameter fluctuations to the odd--even energy difference of the island is small. This confirms the mean-field (BCS) picture of the parity effect.

Single electron tunneling into small superconducting islands is sensitive to the gap energy of the excitations created in the process and, hence, depends on the parity of the electron number in the island. We study these effects by analyzing the kinetics of the system. The tunneling of a single elec
