Spin and orbital contributions to angular momentum are distinguished

Magnetic field influences the angular momentum radiation pattern

Abstract

We investigate the radiation of optical angular momentum by a dipole gas under uniform magnetic field with an unpolarized source at its center. Conservation of angular momentum implies that the radiation of angular momentum results in a torque on both the source and the surrounding environment. Moreover, we study the spin and orbital contributions to the radiated angular momentum.
