Abstract

This study explores the dynamics of a system comprising two two-level atoms, each interacting with a single-mode field in a distinct optomechanical cavity. A particular focus is placed on the role of the detuning parameter in the temporal behavior of physical properties of the system. By deriving the effective Hamiltonian of the system and solving the time-dependent Schrödinger equation, we obtain the state vector of the entire system at any given time. We then quantify the interatomic correlation via quantum discord. Our results demonstrate that the quantum discord between the two atoms can be effectively controlled and engineered by tuning the detuning parameter, the atom-field coupling strength, and the optomechanical coupling.
