Abstract
An exactly solvable local Thomas-Fermi-Dirac approximation is applied to th e calculation of the ground-state density of three-dimensional quantum dot arrays, where we give estimates to properties like total energy, chemical p otential, and differential capacitance. Numeric examples are calculated for pairs of quantum dots using a Gaussian confining potential. The computatio nal complexity of the present method is linear in the number of electrons a nd centers of the system.
