“…Despite the quite developed modern theoretical techniques (see, for example, [1][2][3][4]) for the investigation of quantum optical systems, all the calculations done in this area explicitly or implicitly accept certain kind of approximations to simplify mathematical difficulties arising even in the model with the ''dipole approximated'' atom-field interaction. In this work we discuss still undiscovered anywhere and therefore actual problems that can be counted for the commonly accepted approximations.…”

“…In the above expression we can recognize the first term as the one responsible of spontaneous and stimulated emission processes, while the second one takes into account stimulated absorption, as imposed by the lowering and raising properties of A α (ω). Therefore, if the reservoir is a thermal bath at T = 0 the Corollary 4 tell us that the correct dissipator of the master equation can be obtained by suppressing the stimulated absorption processes in (22).…”

Quantum mechanics must be regarded as open systems. On one hand, this is due to the fact that, like in classical physics, any realistic system is subjected to a coupling to an uncontrollable environment which influences it in a non-negligible way. The theory of open quantum systems thus plays a major role in many applications of quantum physics since perfect isolation of quantum system is not possible and since a complete microscopic description or control of the environment degrees of freedom is not feasible or only partially so [1]. Practical considerations therefore force one to seek for a simpler, effectively probabilistic description in terms of an open system. There is a close physical and mathematical connection between the evolution of an open system, the state changes induced by quantum measurements, and the classical notion of a stochastic process. The paper provides a bibliographic review of this interrelations, it shows the mathematical equivalence between markovian master equation and generalized piecewise deterministic processes [1] and it introduces the open system in an open observed environment model.

“…The twoatom Tavis-Cummings model describes the simplest fundamental interaction between a single mode of quantized electromagnetic field and two atoms under the usual two-level and rotating wave approximations. The atom-field entanglement for two two-level atoms interacting with coherent cavity field by means of one-photon transitions has been studied in [7,8]. The important generalization of considered model is two-atom two-photon Tavis-Cummings model.…”
