Energy spectrum, persistent current and electron localization in quantum rings
M. Manninen, P. Koskinen, M. Koskinen +3
Energy spectra of quasi-one-dimensional quantum rings with a few electrons are studied using several different theoretical methods. Discrete Hubbard models and continuum models are…
Electron-hole bilayer quantum dots: Phase diagram and exciton localization
K. Karkkainen, M. Koskinen, M. Manninen +1
We studied a vertical ``quantum dot molecule'', where one of the dots is occupied with electrons and the other with holes. We find that different phases occur in the ground state,…
Exchange-correlation energy of a multicomponent two-dimensional electron gas
K. Karkkainen, M. Koskinen, S. M. Reimann +1
We discuss the exchange-correlation energy of a multicomponent (multi-valley) two-dimensional electron gas and show that an extension of the recent parametrisation of the exchange-…
