On depolarisation level shift in spherical QD
arXiv:cond-mat/0002319
Abstract
A giant level shift, resulted from the interaction of an electron in a spherical quantum dot with zero--point oscillations of confined modes of the electric field, is divulged. The energy correction depends on the dot radius. This size scaling of the depolarisation effect is computed semiclassically. A change of the optical properties of the matrix surrounding the dot provides a method to study the shift experimentally.
