Spontaneous Emission and Lame Shift in Photonic Crystals
Being motivated by the controversial results based on two dispersion models and Weisskopf-Wigner approximation (WWA), we introduce, for the first time to our knowledge, the position-dependent photon-atom interaction into the Green function method of the evolution operator and develop a universal theoretical approach to study spontaneous emission of atoms in photonic crystals (PCs). A position-sensitive generalized Lorentzian formalism (non-Lorentzian shape) for the decay of an excited atom in...[Show more]
