Quantum Dots with Rashba Spin-Orbit Coupling. Governale, M. Physical Review Letters, 89(20):206802, October, 2002.
Paper doi abstract bibtex We present results on the effects of spin-orbit coupling on the electronic structure of few-electron interacting quantum dots. The ground-state properties as a function of the number of electrons in the dot N are calculated by means of spin-density functional theory. We find a suppression of Hund’s rule due to the competition of the Rashba effect and exchange interaction. Introducing an in-plane Zeeman field leads to a paramagnetic behavior of the dot in a closed-shell configuration and to spin texture in space.
