Abstract
A theoretical analysis of the electronic properties of a few-electron system confined in multiple coupled quantum dots (QDs) is presented. Accurate numerical approaches of the exact diagonalization and Monte Carlo to compute energy spectra and other relevant quantities of the confined many-electron system are described. General features such as single electron tunneling and charge stability diagram in QDs are reviewed. Level crossings with corresponding density variations (rotations) in coupled QD structures with large aspect ratios and their effects on the charge stability diagram and addition energy spectra are then discussed.
