dc.description.abstract | The unrestricted Pople–Nesbet approach for real atoms is adapted to quantum dots under applied magnetic field. Gaussian basis sets are used instead of the exact single-particle orbitals in the construction of the appropriated Slater determinants. Both system chemical potential and charging energy are calculated, as well as the expected values for total spin and its z-component. We have verified the validity of the energy shell structure as well as the Hund rule for state population at zero magnetic field. Above given fields, we have observed a violation of the Hund rule by the suppression of triplet and quartet states at the 1p-energy shell, taken as an example. We have also compared our present results with those obtained by using the LS-coupling scheme for low electronic occupations. We have focused our attention on ground-state properties of GaAs quantum dots populated up to 40 electrons. | pt_BR |
