“Trapping” of the Radiation of an Excited Particle by Its Stark Interaction with the Nonresonant Levels of Surrounding Particles
Ashat M. Basharov · Journal of Experimental and Theoretical Physics Letters · 2018
It has been shown analytically that an excited particle surrounded by immobile unlike atoms does not emit at a certain number of surrounding atoms. The necessary condition is the smallness of the region occupied by the particle and its environment compared to the wavelength of a photon emitted by an isolated particle in electromagnetic vacuum.
