Path integral quantization of the electromagnetic field in nonlinear dielectric materials
Arman Kashef, Oscar Perearnau Herrero, Alexander Szameit +2
We construct a quantum theory of light in nonlinear dielectric media with dispersion and absorption. We employ a mesoscopic model for the light-matter interaction that include a fo…

Nonlinear Quantum Electrodynamics of Epsilon-Near-Zero Nanocavities
Luca Dal Negro, Riccardo Franchi, Marco Ornigotti
We investigate single-photon nonlinear refractive index change and frequency shift of Epsilon-Near-Zero (ENZ) sub-wavelength nanocavities. We apply the rigorous quantum Langevin-no…
