“…Due to its unique optical and electronic properties, a two-dimensional (2D) hexagonal lattice made of closely packed carbon atoms known as graphene has recently gained prominence as a key material for scientific and technological research, including the study of quantum optics [28][29][30]. Because of the magnetooptical properties of graphite layers, absorption maxima occur between Landau levels according to specific selection procedures [31][32][33][34][35][36][37][38]. Later, optical nonlinearity has also been investigated utilizing the appropriate band structure and selection rules [39][40][41], which has several applications, including the power of terahertz (THz) radiation, which has been discovered using four-wave mixing and stimulated Raman scattering with monolayer graphene [42][43][44][45].…”

The optomechanically induced grating (OMIG) in a nanocavity using a bilayer graphene system as the intracavity medium has been proposed. We investigate the effects of different parameters on the Fraunhofer diffraction pattern of the incident probe light. Here, one mirror of the nanocavity is considered coherently driven by the standing wave coupling and probe fields, whereas the second mirror has mechanical oscillation due to the radiation pressure. We consider interaction of bilayer graphene with the optomechanical cavity and show that OMIG can be obtained corresponding to output probe field frequency. Moreover, we find that under specific parametric conditions, most of the probe energy can transfer to the higher orders of the diffraction and only a small portion remains in the zero order.

“…Phenomena such as electromagnetically induced transparency [26], optical bistability (OB) [27][28][29][30], enhanced Kerr effect [31], optical solitons [32] and others [10,[33][34][35][36][37][38] were widely studied by different researchers. Phenomena like these in monolayer graphene system were studied by many researchers to realize all-optical systems [39][40][41][42][43]. For example, Asadpour and Rahimpour Soleimani studied phase control of OB and multistability in a ring cavity doped with a four-level graphene nanostructure in infrared regions [44].…”

In this letter, we have proposed a new model for quantum control of atom photon entanglement in a single layer graphene via von Neumann reduced entropy of entanglement. We consider the effect of terahertz laser field intensity on the degree of entanglement (DEM) in the resonance and off-resonance condition of the applied fields. We also investigate the spatially dependent of the DEM when two applied light becomes standing wave pattern in x and y directions. Our results show that in different parametric conditions, the population of the different states can be controlled and this leads to modifying the DEM of the system.

“…Quantum coherence associated phenomena have been nicely studied in specific coherent systems due to their applications in quantum information science [1,2]. For example, Goos-Hänchen shifts [3,4], refractive index [5], slow and fast light [6,7], four-wave mixing (FWM) [8], optical solitons [9] and other phenomena [10][11][12][13] have been discussed and evolved in numerous systems [14][15][16][17][18]. One of the most exciting phenomena in quantum and nonlinear optics is optical bistability (OB) and optical multistability (OM) [19,20].…”

In this article, we have proposed a unique approach to adjust optical bistability (OB) and optical multistability (OM) in a ring cavity inclusive of a three-level quantum system primarily based on quantum mean-field theory. The quantum system interacts with a weak probe light, an incoherent pumping field and a robust coupling light which carries an optical vortex that is an electromagnetic light with optical angular momentum. We confirmed that the real and imaginary parts of the susceptibility of the no-vortex probe light relies on the azimuthal angle and orbital angular momentum (OAM) of the vortex light whilst the quantum interference time period will become important. Moreover, we determined that because of the OAM number of vortex light, the switching from OB to OM is feasible for extraordinary azimuthal angle. These functions of such a three-level quantum system are not stated in any comparable studies.
