Restricted and unrestricted Hartree-Fock approaches for addition spectrum and Hund's rule of spherical quantum dots in a magnetic field

C. F. Destefani, J. D. M. Vianna, G. E. Marques

The Roothaan and Pople-Nesbet approaches for real atoms are adapted to quantum dots in the presence of a magnetic field. Single-particle Gaussian basis sets are constructed, for ea…
