Abstract:The concept of photonic frequency (ω) -momentum (q) dispersion has been extensively studied in artificial dielectric structures such as photonic crystals and metamaterials. However, the ω − q dispersion of electrodynamic excitations hosted in natural materials at the atomistic level is far less explored. Here, we develop a Maxwell Hamiltonian theory of matter combined with the quantum theory of atomistic polarization to obtain the electrodynamic dispersion of natural materials interacting with the photon field… Show more
