“…In addition, the coupling coefficient η c is assumed to be a constant, and the specific value η c = 1/2. Using the rotating wave approximation of the system, the full Hamiltonian o system, as shown in Figure 1, can be written as [26,27,32,34] Based on the Hamiltonian in Equation ( 1) and considering the damping of the cavity field and phonon field, the quantum dynamic evolution of the system can be described by the following Heisenberg-Langevin equation [33,35]:…”

“…In recent years, there has been a growing interest in nonlinear optical-mechanical effects within cavity optomechanical systems. By considering the nonlinear interaction term in the dynamic equation of an optical-mechanical system, many interesting phenomena caused by nonlinear optical-mechanical interactions have been revealed, and the scope of cavity optical-mechanical systems has been expanded to topics such as the generation of second-order sidebands [28][29][30], sideband frequency combs [31], optical-mechanical chaos [32], photon-blockade effects [33,34] and carrier-envelope phase correlation effects [35,36]. Among these phenomena, OSS is the first non-linear sideband of the higher-order sidebands, and the generation of high-order sidebands stands out as a characteristic manifestation of nonlinear interactions.…”

We propose an efficient scheme to enhance the generation of optical second-order sidebands (OSSs) in an atom-assisted optomechanical system. The cavity field is coupled with a strong driving field and a weak probe field, and a control field is applied to the atom. We use the steady-state method to analyze the nonlinear interaction in the system, which is different from the traditional linear analysis method. The existence of an auxiliary three-level atom driven by the control field significantly enhances the generation of an OSS. It is found that the efficiency of the OSS can be effectively modulated by adjusting the Rabi frequency of the control field, optomechanical cooperativity and atomic coupling strength. Our scheme provides a promising solution for controlling light propagation and has potential application in quantum optical devices and quantum information networks.

“…UPB was firstly proposed in a system consisting two coupled quantum boxes in 2010 [30]. Subsequently, many systems were constructed to realize the UPB, such as coupled optomechanical systems [31][32][33], quantum dots coupled to dual-mode optical cavities [34,35], coupled nonlinear resonators [36], rotating cavities in degenerate optical parametric amplifiers [37][38][39].…”

In this paper, the photon blockade effect in a three-wave mixing coupling system with a quantum dot has been studied. By using analytical calculation and numerical analysis, we find that both the conventional photon blockade and the unconventional photon blockade effects could be realized in this system in strong-coupling regime just by one driving. Besides, compared with Jaynes-Cummings model, this hybrid system shows other obvious advantages in realizing the photon blockade, like blockading photon of more different frequencies, stronger antibunching effect, and so on. All the results may provide useful theoretical references for the single-photon devices designing by using quantum dot and three-wave mixing system in future experiments and applications.

“…Recently, much attention has been paid to the study of cavity optomechanical systems with linear coupling [18][19][20][21][22][23], comprising the radiation-induced pressure interaction between light and mechanical motion in the macroscopic scale. These types of systems possess a broad range of important applications, which include the ability to generate different bipartite [24] and tripartite [25] entanglements and sensitive measurements of mechanical motion [26][27][28], photon blockade [29][30][31], phonon blockade [32,33] and optical squeezing, which were investigated from both theoretical and experimental points of view [34][35][36]. An extension of such systems is an optomechanical system with second-order, i.e., quadratic coupling, wherein nonlinear interaction between photons and phonons provides conditions for performing many interesting phenomena, especially squeezing [37][38][39], photon blockade [40][41][42], which was first presented by Rabl et al [43,44], and phonon blockade [45][46][47][48][49].…”

In this paper, we present a theoretical scheme for the generation and manipulation of bipartite atom–atom entanglement in a dissipative optomechanical system containing two atoms in the presence of linear and nonlinear (quadratic) couplings. To achieve the goal of paper, we first obtain the interaction Hamiltonian in the interaction picture, and then, by considering some resonance conditions and applying the rotating wave approximation, the effective Hamiltonian, which is independent of time, is derived. In the continuation, the system solution was obtained via solving the Lindblad master equation, which includes atomic, optical and mechanical dissipation effects. Finally, bipartite atom–atom entanglement is quantitatively discussed, by evaluating the negativity, which is a well-known measure of entanglement. Our numerical simulations show that a significant degree of entanglement can be reached via adjusting the system parameters. It is noticeable that the optical and mechanical decay rates play an important role in the quasi-stability and even stability of the obtained atom–atom entanglement.
