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…
