Generalized Cloaking and Optical Polyjuice
A. Nicolet, F. Zolla, C. Geuzaine
In this paper, a generalization of cloaking is presented: instead of an empty region of space, an inhomogeneous structure is transformed via Pendry's map in order to give, to any o…
Absorption in quantum electrodynamics cavities in terms of a quantum jump operator
V. Debierre, G. Demésy, T. Durt +3
We describe the absorption by the walls of a quantum electrodynamics cavity as a process during which the elementary excitations (photons) of an internal mode of the cavity exit by…
Bloch vector dependence of the plasma frequency in metallic photonic crystals
D. Felbacq, F. Zolla, G. Bouchitte
We show that the plasma frequency in wire photonic crystals depends upon the Bloch vector. An accurate formula is given.
Do Fresnel coefficients exist?
D. Felbacq, B. Guizal, F. Zolla
The starting point of the article is the puzzling fact that one cannot recover the Fresnel coefficients by letting tend the width of a slab to infinity. Without using the so-called…
Spontaneous light emission by atomic Hydrogen: Fermi's golden rule without cheating
V. Debierre, T. Durt, A. Nicolet +1
Focusing on the transition in atomic Hydrogen, we investigate through first order perturbation theory the time evolution of the survival probability of an…
Quasinormal mode solvers for resonators with dispersive materials
P. Lalanne, W. Yan, A. Gras +16
Optical resonators are widely used in modern photonics. Their spectral response and temporal dynamics are fundamentally driven by their natural resonances, the so-called quasinorma…
