Abstract
The optical absorption of a single spherical semiconductor quantum dot in an electrical field is studied taking into account the nonlocal coupling between the electric field of the light and the polarizability of the semiconductor. These nonlocal effects lead to a small size and field dependent shift and broadening of the excitonic resonance, which may be of interest in future precision experiments.
