The two-photon interaction process of N identical three-level atoms with squeezed light is considered. The dependence of the absorption process on the squeezed fluctuations of light is studied. It is shown that the absorption rate of phase squeezed light is larger than the absorption rate of...

A Fokker-Planck-type equation is derived in the second order perturbation theory for the density matrix, which describes the time evolution of a single-particle system (proton or ion) weakly interacting with a large system (crystal). This equation is suitable for the description of the motion of...

The propagation of few-cycles optical pulses in a collection of two-level atoms is investigated beyond the traditional slowly varying envelope approximation. It is shown that in certain conditions, a femtosecond pulse can evolve into a stable spatiotemporal optical soliton.
