“…Quantum mechanical systems enable numerous breakthroughs that classical systems cannot reach [1][2][3]. In this regard, the ability to generate and manipulate non-classical (quantum) characteristics has been discussed in various schemes such as cavity quantum electrodynamics (QED) [4][5][6], optomechanics [7][8][9], cavity magnonics [10][11][12], and magnomechanics * Author to whom any correspondence should be addressed.

Magnon and photon blockade implementation and manipulation have significant practical applications in quantum information processing and quantum metrology due to their tight relations to single-photon and -magnon source devices. In this paper, we propose an experimentally feasible hybrid scheme for the dynamical description of the tripartite interacting system consisting of magnon and phonon modes with photons in an optomechanical system, from which we aim to explore the quantum statistics, as well as the magnon and photon blockade phenomenon. To achieve the purpose, the dissipative solution of the system is obtained with the help of the Lindblad master equation. Via employing the equal-time second-order correlation function and using the steady state solution of the system, the statistics and blockade effects of magnon and photon are analyzed and also their dependence on the parameters involved in the system are discussed. Utilizing feasible parameters, our simulations illustrate that, sub-Poissonian behavior and therefore, blockade of magnon and photon are simultaneously achieved. More importantly, the mentioned blockade effects can be obtained in a range of parameters (and not with specific) which makes our proposal easy to access, experimentally. Considering the above realizations, the introduced scheme opens up a pathway to design single-magnon and - photon generators, which are of crucial importance in advanced quantum science and technologies.

“…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]. Now, we continue with referring to the literature dealing with linear and nonlinear optomechanical cavities with more details on the squeezing and blockade that have been of interest in these systems.…”

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.
