Polarization and Magnetization Fields: A “Post-Modern” Theory by Prof. John E. Sipe
Our first speaker was a pioneer in the field of theoretical quantum optics - Prof. John Sipe from the University of Toronto. He talked about the response of solids to incident electromagnetic fields which is often heuristically described in terms of macroscopic polarization and magnetization fields...
Quantum field theory for spin operator of the photon
Our latest paper reports on the discovery of the photon spin operator. All particles in nature can be classified as fermions or bosons. The key distinguishing characteristic is their spin, an internal angular momentum. We stumbled on the spin operator of bosonic gauge fields using quantum...
