QUANTUM DYNAMICS OF A CHARGED PARTICLE IN THE FIELD OF A PLANE ELECTROMAGNETIC WAVE IN A MEDIUM AT A STRONG COUPLING

摘要

Within the framework of relativistic quantum theory, the nonlinear interaction of a charged particle with a coherent electromagnetic wave in a dielectric medium at the strong "particle-wave" coupling is studied. It is shown that, in contrast to weak coupling, when the band structure of coupled states of a particle in the wave takes place, in strong coupling the spectrum of states has a discrete character, and resonant radiative transitions between these states are possible.
