Ground state energy fluctuations of interacting electrons in disordered quantum dots

Research output: Contribution to journalArticle

Abstract

The distribution of the peak spacings of Coulomb oscillation is theoretically investigated in disordered quantum dots. Taking account of the electron-electron interaction by the perturbation, we show that a pair-type (BCS-type) correlation plays an important role in determining the distribution, which could deviate drastically from the prediction of the random matrix theory. A possible mechanism of a sharp peak structure is proposed, which is in accordance with numerical results.
