| Research Abstract |
A quantum chemical code for calculating electronic states of artificial atoms involving magnetic impurities has been developed for the purpose of designing an ultrafast scheme of controlling atomic spins by laser lights. Numerical simulations of optical spectra for the studied systems have shown a possibility of controlling spin states of the magnetic impurities by properly choosing their number and spatial configuration. Analysis of the electronic structure of artificial atoms has clarified the origin of Hund's multiplicity rule that operates in artificial atoms as well as in usual atoms.
