  We address the dynamical bipartite entanglement in an opto-electro-mechanical
system that involves a three-level atom. The system consists of a degenerate
three-level atom, a mechanical resonator, an optical cavity, and a microwave
cavity. By utilizing the linearization approximation and nonlinear
quantum-Langevin equations, the dynamics of the system are analyzed, and the
bipartite entanglement is evaluated using the logarithmic negativity. The
research findings indicate that the entanglement between each subsystem
increases with the atom injection rate, suggesting that a higher atom injection
rate leads to enhanced information transmission between the subsystems.
Additionally, it is observed that the correlation between subsystems increases
with an increase in the coupling rate. Moreover, the study demonstrates that
the correlation between each subsystem decreases as temperature rises. The
results highlight the positive impact of three-level atoms on the bipartite
entanglement in an opto-electro-mechanical system. Consequently, such
electro-optomechanical systems can offer a framework for optomechanical
information transfer.
