Abstract

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 nanosphere. It is then shown that the Lamb shift resonance can be blueshifted as the size of the nanoparticle increases, suggesting that nanoparticles may be used to tune this resonant interaction. Finally, a realistic calculation of the Lamb shift is made for a dimer configuration.
