Abstract

We present ground-state calculations for laterally coupled quantum dots containing two, four, and eight electrons. As our emphasis is on spin effects our results are obtained by applying spin-density functional theory (SDFT). By varying the distance between the centers of the coupled quantum dots, the transition from the weak- to strong-coupling situation is realized. For the two-electron system ...
