РАВНОМЕРНО ПРИГОДНОЕ ПРИБЛИЖЕНИЕ ДЛЯ ХАРАКТЕРИСТИК ЭЛЕКТРОМАГНИТНОГО ПОЛЯ В КВАНТОВОЙ МОДЕЛИ РАБИ

Efficiency of the uniformly available approximation for description of the quantum Rabi model beyond the rotating wave approximation is systematically investigated. Correlation characteristics of the electromagnetic field in a resonator are calculated and some physical effects due to presence of the counter-rotating terms in the Hamiltonian are considered.
