The monodromic axion-photon coupling
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 FF~ of the photon. We show that the non-linearity of g(a) is...
