Few-electron artificial molecules formed by laterally coupled quantum rings
T. Chwiej, B. Szafran
We study the artificial molecular states formed in laterally coupled double semiconductor nanorings by systems containing one, two and three electrons. An interplay of the interrin…

Exciton and negative trion dissociation by an external electric field in vertically coupled quantum dots
B. Szafran, T. Chwiej, F. M. Peeters +3
We study the Stark effect for an exciton confined in a pair of vertically coupled quantum dots. A single-band approximation for the hole and a parabolic lateral confinement potenti…

Spatial ordering of charge and spin in quasi one-dimensional Wigner molecules
B. Szafran, F. M. Peeters, S. Bednarek +2
ew-electron systems confined in quasi one-dimensional quantum dots are studied by the configuration interaction approach. We consider the parity symmetry of states forming Wigner m…
