What is Poynting Vector in Axion Electrodynamics about?
This document discusses two versions of the Poynting theorem - the Abraham and Minkowski forms - in the context of axion modified electrodynamics. When axions convert to photons via interaction with a background magnetic field, this process is nonconservative with respect to the created photonic degree of freedom. The study finds that the Minkowski form correctly accounts for these additional nonconservative "curl force" terms, while the Abraham form does not. For resonant cavity axion detectors, both forms
