SPIN CONFIGURATION IN THE ELECTRON MOLECULE IN FEW-ELECTRON QUANTUM DOTS IN STRONG MAGNETIC FIELDS — SUPERPOSITION OF MULTIPLE CONFIGURATIONS

Abstract

Electron correlation in molecular quantum dot states is examined with an exact dot model and a Hubbard model. The orbital and spin angular momentum of a 5-electron dot in the ν < 1 regime are consistent with the occurrence of a superposition 4- and 5-fold configurations. Hubbard model correlation functions are calculated for these configurations. Spin summed pair correlation functions agree well with the exact results but there are differences in the spin resolved functions.
