S. Klama, THE ELECTRON-ENERGY SPECTRUM OF A CIRCULAR RING IN AN EXTERNAL MAGNETIC-FIELD, Journal of physics. Condensed matter, 5(31), 1993, pp. 5609-5622
The dynamics of two-dimensional electrons in a circular ring in an ext
ernal perpendicular magnetic field is investigated. The boundaries of
the ring are approximated by infinite potential barriers. Within the q
uasiclassical approximation, a complete classification of the electron
states generated by confinement and magnetic field is provided.
