“…Its considered as a phenomenon that describe the collapses and revivals of the states. We can evaluate the population inversion for the proposed model by the variation between the probabilities of the system existence in its exited state |e and in its ground state |g [27,38,39].…”

We propose a scheme to investigate the behavior of a ballistic nanowire system with Rashba interaction within a perpendicular magnetic field. The quantum entanglement of a nanowire system is discussed via the negativity. When the strong and weak magnetic fields are applied, we discuss the influence of the spin-orbit interaction and the initial states on the population inversion and the negativity. Our results show that the degree of entanglement for the nanowire system mainly depends on the effect of the spin-orbit interaction and the initial states of the system. This opens up new avenues for designing nanowire systems for future quantum computation and communication applications.

“…The interaction between SU(1,1) and SU(2) quantum systems have been studied by many authors [14,29]. The effect of damping reservoir for even case of Barut-Girardello states at k = 1/4 have been discussed [30]. The influence of coupling parameters of the external classical field system on the SU(1 ,1) and SU(2) interaction have been examined [31,32].…”

The effect of nonlinearity, initial atomic state, and different resonance cases on the interaction between nonlinear SU (1, 1) quantum states and a two-level atom is discussed. The optimal behaviours of decoherence, entanglement and quantum coherence are predicted via using the skew information, tomographic entropy, and the relative entropy of coherence, respectively. It is shown that the detuning parameter has a destructive effect on the coherence and consequently on the entanglement if the quantum system is regulated in the ideal SU (1, 1) quantum systems. For the nonlinear SU (1, 1) quantum systems, the ability to suppress the decay of entanglement induced by the detuning may be increased by preparing the initial atomic state in its excited state.

“…A theoretical schemes for generation of two distinct groups of the correlated nonlinear coherent state based on SU(1,1) and SU(2) are presented, by choosing particular f-deformation functions [20]. The properties of the SU(1,1) interaction with SU(2) in presence of cavity damping depending on SU(1,1)-cavity damping has been studied [21][22][23]. Quantum correlation has been studied for a system consisting of two isolated bits, each interacting with a single-mode cavity in [24].…”

A nonlinear interaction between SU(1,1) quantum system and a three-level atom in different configurations with damping term

The effect of nonlinear medium and phase damping is investigated on an atom of three levels in different forms interacting with the SU(1,1) Lie algebra. The SU(1,1) system starts the interaction from the Perelomov coherent state, while the atom starts the interaction from excited-most state. The time dependent wave function is calculated by using the Schrödinger equation. The density matrix is obtained. The influences of damping, nonlinearity (Kerr-like medium), Perelomov coherent parameter and the Bargmann index on some non-classical properties, such as: revivals-collapses phenomenon, entanglement and atomic variables squeezing, are investigated.
