| contents | An approach to the theoretical study of effects and phenomena in quantum gases interacting with radiation is proposed. The approach is based on a modification of the canonical transformation method, which was once used to diagonalize Hamiltonians describing the interaction of electrons with phonons in a solid. The capabilities of the method are demonstrated by studying the influence of photons on the spectral characteristics of atoms of quantum gases interacting with radiation. Within the framework of the developed approach, the effect of "dressing" atoms of quantum gases by a cloud of virtual photons is investigated and expressions for the energy characteristics of such dressed atoms - quasiparticles are obtained. The problem of defining the concept of the effective mass of such quasiparticles is discussed. |
