Density-functional theory of multicomponent quantum dots

Karkkainen, K ; Koskinen, M ; Reimann, Stephanie LU and Manninen, M (2004) In Physical Review B (Condensed Matter and Materials Physics) 70(19).
Abstract
Quantum dots with conduction electrons or holes originating from several bands are considered. We assume the particles are confined in a harmonic potential and assume the electrons (or holes) belonging to different bands to be different types of fermions with isotropic effective masses. The density-functional method with the local density approximation is used. The increased number of internal (Kohn-Sham) states leads to a generalization of Hund's first rule at high densities. At low densitites the formation of Wigner molecules is favored by the increased internal freedom.
