Axion electrodynamics: Energy-momentum tensor, and possibilities for experimental tests

Iver H. Brevik, Moshe M. Chaichian

Axion electrodynamics is based upon the Lagrangian of the electromagnetic (EM) field plus its interaction with the axions, and is accordingly a physically open system. It means tha…
