Persistent current oscillations in electron-hole quantum dots

Abstract: A system of Kohn–Sham equations was solved self-consistently for the two-dimensional, spatially separated electrons and holes. A series of magic numbers were found for the total angular momentum of the electrons and holes in a strong magnetic field. The change of the angular momentum of the charge carriers was shown to lead to oscillations of the persistent current.

Keywords: electron-hole quantum dots, the Kohn–Sham equations, persistent current.
