THE PATH INTEGRAL APPROACH FOR THE TWO-PHOTON RABI OSCILLATIONS DESCRIPTION
The description of two-photon Rabi oscillations between Rydberg states of calcium is considered. For that the quantum transitions probability are represented as a path integral of real functional, using path integral formalism in energy representation. We perform numerical simulation of the atoms populations dynamics without the rotating wave approximation for different values of the electric field amplitude. The obtained results compared with experimental data.
