摘要

In this article, by using the perturbation theory, we analytically solve the eigenvalue problem for the Hamiltonian describing the interaction of Lambda-type three-level atom with a single-mode radiation field without the rotating wave approximation (RWA). For this purpose, the atom-field interaction Hamiltonian, which contains the counter-rotating terms (CRTs), is transformed to an analytically solvable Hamiltonian by applying three successive unitary transformations.
