摘要：

We computed the electronic structure of a circular parabolically confined 2-D quantum dot and a quantum dot molecule in an external magnetic field, The modeled systems are a single six-electron quantum dot and a quantum dot molecule comprising two one-electron dots. The calculations were done in real space using current and spin density functional theory. The results are compared to those obtained by the quantum Monte Carlo method.
