Local field and radiative relaxation rate in a dielectric medium

The effect of atomic and optical perturbations on formation and propagation of vortex solitons in a dense atomic media of gas-filled hollow-core optical fibers

“…However, for the media with a large density of optically active particles, it is necessary to take into account the effective or the local value of the field acting on them [16][17][18][19][20]. The atom-field interaction in this case becomes more complicated.…”

Spectroscopy of single organic dye-molecules and semiconductor quantum dots: basic aspects and applications in nanoscopy

“…In particular, it is proposed to use our approach to nanodiagnostics (mapping) of the local fields in solids, as well as creating a microrefractometry technique [15]. The basis of this approach is the fact that at ultralow temperatures the width of the SM ZPL is determined only by the lifetime of the excited state T1, which, due to the local field effects, is associated with the effective value of the refractive index of the medium [16,17]. Thus, the ZPL width value may be converted to an effective value of the refractive index in the local neighborhood of each registered SM.…”

Cooperative effects and slow dynamics of fluorescence intensity from quantum emitters in a dielectric

“…We use a generalized system of optical Bloch equations derived for an emitter in an ensemble of motionless similar particles embedded in a dielectric medium, which is transparent for the incident light [3][4]. The system is written with the effective rates of individual and collective radiative relaxation rates of the emitters, the Rabi frequency, and the effective transition-frequency shift caused by the presence of the dielectric host.…”

“…In other words, there may be conditions for multiple steady-state populations and polarizations of the particles, realizable for the same external parameters. The presence of the material that hosts the light emitters brings changes and must be considered carefully even if it is a pure dielectric and any other interactions, like phonons, are neglected using valid approximations [3].We use a generalized system of optical Bloch equations derived for an emitter in an ensemble of motionless similar particles embedded in a dielectric medium, which is transparent for the incident light [3][4].
