Abstract
Radiation from a localized, oscillating charge distribution can have angular momentum that cannot be explained in classical electrodynamics. We consider the simplest example -- electric dipole radiation of a single photon -- and show that this angular momentum is attributable to zero-point oscillations in unexcited states of the dipole source.
