T. K., M. O. and collaborators performed experiments using non-metallic materials under non-resonant and/or forbidden-transition conditions, showed various phenomena not observed in conventional optics, and explained in terms of dressed photons. From a viewpoint of response theory, such the conditions, e.g., dipole-forbidden condition, the non-resonant term of the response function dominates over the null or suppressed resonant term, so that diamagnetic current density appears as the result of response to the imposed vector potential, instead of the electric field. The fundamental reason of the logical fallacy of the electric field in the previous presentation lies in this fact. In this presentation, we try to give a simultaneous explanation for the high efficient light emission and giant magneto-optical rotation angle of photon breeding devices. We will also pointed out the relationship between such the DP system and the superconductor system.
