It is now well established that radiative decay of quantum emitters can be strongly modified by their environment. In this paper, we present an exact—within the weak-coupling approximation—multipole expression to compute the Lamb (frequency) shift induced by an arbitrary set of resonant scatterers on a nearby quantum emitter, using multiscattering theory. We also adopt a quasi-normal mode description to account for the line shape of the Lamb shift spectrum in the near field of a plasmonic…

The spectral and spatial dependence of the resonant Lamb shift of an exciton inside a photonic vacuum field landscape is considered to predict an optical dipole potential generated via virtual
Quasi-static method and finite element method for obtaining the modifications of the spontaneous emission rate and energy level shift near a plasmonic nanostructure.
We provide numerical demonstrations of the applicability and accuracy of the quasi-static method and the finite-element method in the investigation of the modifications of the spontaneous emission
Influence of Surface Roughness on Strong Light-Matter Interaction of a Quantum Emitter-Metallic Nanoparticle System
An exact quantum optics approach is derived to obtain the field enhancement and light-emission spectrum of a quantum emitter and shows that the surface roughness has a greater effect on the near-field than on the far-field, and slightly increases the vacuum Rabi splitting.
Impulsions électromagnétiques dans des milieux ultra-dispersifs nanostructurés : une approche théorique et numérique
L’etude de l’interaction entre une impulsion electromagnetique et un materiau dispersif est un vieux sujet qui remonte au moins au tournant du vingtieme siecle avec Sommerfeld et Brillouin. Depuis


Fluorescence relaxation in the near-field of a mesoscopic metallic particle: distance dependence and role of plasmon modes.
It is demonstrated that near-field coupling can be expressed in a simple form verifying the optical theorem for each particle modes and the electromagnetic coupling mechanisms between the emitter and the particle.
Theory of the spontaneous optical emission of nanosize photonic and plasmon resonators.
A self-consistent electromagnetic theory of the coupling between dipole emitters and dissipative nanoresonators that predicts that a spectral detuning between the emitter and the resonance does not necessarily result in a Lorentzian response in the presence of dissipation.
Decay of an excited atom near an absorbing microsphere
Spontaneous decay of an excited atom near a dispersing and absorbing microsphere of given complex permittivity that satisfies the Kramers-Kronig relations is studied, with special emphasis on a
Giant lamb shift in photonic crystals.
The photonic-crystal environment can lead to very large values of the Lamb shift, as compared to the case of vacuum, and the position-dependent Lamb shift should extend from a single level to a miniband for an assembly of atoms with random distribution in space, similar to the velocity-dependent Doppler effect in atomic/molecular gases.
Radiative frequency shift and linewidth of an atom dipole in the vicinity of a dielectric microsphere
The frequency shift and linewidth variation of an oscillator placed next to a dielectric microsphere are found within the framework of the classical approach. Both the frequency shift and the

The classical theory of dipole radiation is used to calculate the change in frequency of an electric-dipoleallowed transition due to the presence of a nearby reflecting surface. The result is
