Our theoretical study on dressed photon (DP) was initiated by the important recognition, provided by Greenberg-Robinson theorem, that the involvement of off-shell spacelike momenta is necessary for nonlinear quantum field interactions to occur. As the first step of our research, we successfully extended Maxwellian field of electromagnetism so as to include its spacelike momenta. The implication of this extension of electromagnetic field was far beyond imagination and it not only led us to a novel realm of nano-photonics but also to the cutting-edge research themes in theoretical physics and cosmology. In this talk, focusing only on DP dynamics, the present status of on-going researches will be explained briefly.
