We propose a scheme to enhance entanglement and asymmetric steering between two
mechanical oscillators in an optomechanical system with coherent feedback control. In the …

Quantum coherent feedback control (CFC) has been widely applied to prepare and
manipulate nonclassical beams. In this paper, we utilize an optical beam splitter with tunable …

We investigate the response of quantum entanglement to feedback control in an
optomechanical system which is controlled by the feedback optical field. We concluded that …

We propose a hybrid cavity–magnon optomechanical system incorporating mechanical
nonlinearity to enhance both bipartite and tripartite entanglement. This system consists of a …

We theoretically analyze the transmission characteristics of a magnon–photon coupling
system based on ultrastrong optomechanical-like coupling via the cross-Kerr interaction. We …
