Effect of assisted hopping on the formation of local moments in magnetic impurities and quantum dots
arXiv:cond-mat/0212080 · doi:10.1103/PhysRevB.67.195104
Abstract
Assisted hopping effects in magnetic impurities and quantum dots are analyzed. The magnitude of the assisted hopping term in a quantum dot in the limit of large level spacing is comparable to other corrections induced by the electron-electron interactions. Assisted hopping leads to differences between conductance peaks associated to the same level, and, when the effect is sufficiently strong, to local pairing correlations.
