Lorentz local-field effects on spontaneous emission in dielectric media - art. no. 013801

The recent first-principles derivation of Langevin-Bloch equations of motio n for near-resonant atoms embedded in a linear dielectric host leads to a c lear, direct physical reinterpretation of fundamental physical principles a s applied to one of the most basic problems of quantum mechanics: the renor malization of the spontaneous emission rate of an atom in a dielectric host . Here we show the role of the Lorentz local field, the fluctuation-dissipa tion theorem, the wave number and wave vector, the density of states, Fermi 's golden rule, the electromagnetic energy density, canonical quantization, and the classical constitutive relations in this context.
