Quantum properties in dynamically modulated cavity magnomechanical systems

We theoretically investigate entanglement generation and cooling effects in a cavity magnomechanical system under simultaneous periodic modulation of microwave and magnetic driving fields. We find that in the presence of the parameter modulation, the bipartite and tripartite entanglement and ground-state cooling of the mechanical mode can be generated simultaneously regardless of whether the microwave cavity operates in the red- or blue-detuning region. Further, we demonstrate that the combined modulation of the cavity field and magnon mode is particularly effective in promoting both cooling and entanglement. In particular, by making the asymptotic dynamical behaviour of the system quasiperiodic, the entanglement and cooling dynamics in the system will also exhibit quasiperiodic behaviour, which allows quantum properties in a modulated cavity magnomechanical system to be witnessed through the underlying nonlinear classical dynamics. Our study provides an effective approach to control dynamically the bipartite and tripartite entanglement, which may have potential implications in quantum information processing and quantum regulation.
