Two-electron lateral quantum-dot molecules in a magnetic field
arXiv:cond-mat/0505314 · doi:10.1103/PhysRevB.72.205329
Abstract
Laterally coupled quantum dot molecules are studied using exact diagonalization techniques. We examine the two-electron singlet-triplet energy difference as a function of magnetic field strength and investigate the magnetization and vortex formation of two- and four-minima lateral quantum dot molecules. Special attention is paid to the analysis of how the distorted symmetry affects the properties of quantum-dot molecules.
