The monodromic axion-photon coupling
Abstract We consider the general form of the axion coupling to photons in the axion-Maxwell theory. On general grounds this coupling takes the form of a monodromic function of the axion, which we call g(a), multiplying the Chern-Pontryagin density F F ~ $$ F\overset{\sim }{F} $$ of the photon. We sh...
