Fixed-N Superconductivity: The Crossover from the Bulk to the Few-Electron Limit
Fabian Braun, Jan von Delft
We present a truly canonical theory of superconductivity in ultrasmall metallic grains by variationally optimizing fixed-N projected BCS wave-functions, which yields the first full…

Superconductivity in Ultrasmall Metallic Grains
Fabian Braun, Jan von Delft
We develop a theory of superconductivity in ultrasmall (nm-scale) metallic grains having a discrete electronic eigenspectrum with a mean level spacing of order of the bulk gap. The…
