“…A theoretical framework for cavity optomagnonics has been established to overcome the shortcoming in this field [25][26][27][28][29][30][31]. It is to be expected that the strong optomagnonic coupling will be achieved in the future, opening the door for the applications such as optical cooling the magnons [32], preparation of magnon Fock state [33], and magnon-based photon blockade [34].…”

We present a proposal to test Bell inequality in the emerging field of cavity optomagnonics, where a sphere of ferromagnetic crystal supports two optical whispering gallery modes and one magnon mode. The two optical modes are driven by two laser pulses, respectively. Entanglement between magnon mode and one of the two optical modes will be generated by the first pulse, and the state of magnon mode is subsequently mapped into another optical mode via the second pulse. Hence correlated photon-photon pairs is created out of the cavity. A Bell test can be implemented using these pairs, which enables us to test local hidden-variable models at macroscopic optomagnonical system. Our results show that a significant violation of Bell inequality can be obtained in the experimentally relevant weak-coupling regime. The violation of Bell inequality not only verifies the entanglement between magnons and photons, but also implies that cavity optomagnonics is a promising platform for quantum information processing tasks.

“…Optical microcavity [1], [2], [3] is widely studied for its high quality factor and small mode volume. Recently, the study of microcavity non-linearity including kerr nonlinearity [4], [5], [6], [7], [8], [9], [10], Raman nonlinearity [11], [12], [13], optomechanically induced nonlinearity [14], [15], [16], [17], [18], [19], [20], [21], optomagnonics microcavity [22], [23], [24], [25], [26] become hot points. Combine the nonlinearity and high quality factor of the optical microcavity, various low threshold nonlinear phenomenons such as chaos [27], [28], [29], [30], [31], [32], [33] and frequency comb [34], [35], [36], [37] in the optical microcavity [38], [39] can be observed.…”

Dispersion and dissipation are the key parameters of the optical components. Generally, dissipation is an unfavorable factor that needs to be reduced in an optical equipment. In this article, we designed a dispersion-dissipation hybird coupled optomechanical cavity and achieved dissipation-assisted frequency comb and chaos generation. We studied the bistable state and the stability of the optomechanical cavity and the spectrum of the system. We found that even when the dissipative coupling is about 0.1 or 0.2 times the dispersion coupling strength, chaos and frequency comb can be effectively adjusted by adjusting the dissipative coupling. We given out the formation mechanism of the two types of frequency combs under the nonlinearity of the optomechanical cavities. Our result provides an effective method for achieving low threshold, adjustable frequency comb and chaos in optical microcavity.

“…Usually, the destructive interference and the single excitation resonance resulting from dressed states can supply a better blockade than the Kerr effect because of the weak coupling strength of the Kerr interaction. The photon blockade in an optomechanical system [25] as well as in an optomagnonic system [37] were separately thoroughly investigated. A magnon blockade via qubit-magnon coupling has been studied in Ref.…”

The hybrid microwave optomechanical-magnetic system has recently emerged as a promising candidate for coherent information processing because of the ultrastrong microwave photon-magnon coupling and the longlife of the magnon and phonon. As a quantum information processing device, the realization of single excitation holds special meaning for the hybrid system. In this paper, we introduce a single two-level atom into the optomechanical-magnetic system and show that an unconventional blockade due to destructive interference cannot offer a blockade of both the photon and magnon. Meanwhile under the condition of single excitation resonance, the blockade of photon, phonon, and magnon can be achieved simultaneously even in a weak optomechanical region, but the phonon blockade still requires the cryogenic temperature condition.
