Ultrasensitive detections have been proposed as an application of optomechanical systems. Here we develop an approach to mass sensing by comparing the detected quadratures of light field coupled to a mechanical resonator, whose slight change of the mass should be precisely measured. The change in the mass of the mechanical resonator will cause the detectable difference in the evolved quadrature of the light field, to which the mechanical oscillator is coupled. It is shown that the ultra-small change ∆m from a mass m can be detected up to the ratio ∆m/m ∼ 10 −8 − 10 −7 by choosing the feasible system parameters.

“…We adopt an approach of factorizing a system's evolution operator [53][54][55][56][57][58][59][60][61] to study the system. For the currently concerned evolution operator U (t) = T exp{−i t 0 dτĤ(τ )}, the reservoirs' action manifests by the stochastic Hamiltonian (3) among the total Hamiltonian H(t).…”

“…Then single trapped ions and quantum dots have been utilized in the fields of phonon laser [43,44,45]. Up to now, numerous theoretical and experimental researches have been proposed, such like the cavity optomechanicsbased ultralow-threshold phonon lasers [39], the PT -symmetric phonon laser with balanced gain and loss [40], the nonreciprocal phonon lasing in a coupled cavity system [41], the phonon laser operating at an exceptional point [46], the scheme of amplifying phonon laser by using phonon stimulated emission coherence [47], the phonon-stimulated emission in cryogenic ionic compounds [48,49], semiconductor superlattices [50] and so on [51,52,53,54]. In addition, phonon laser have also attracted extensive interest in medical imaging and high-precision measurement equipment.…”

Using phonons to simulate an optical two-level laser action has been the focus of research. We theoretically study phonon laser in a cavity magnomechanical system, which consist of a microwave cavity, a sphere of magnetic material and a uniform external bias magnetic field. This system can realize the phonon-magnon coupling and the cavity photon-magnon coupling via magnetostrictive interaction and magnetic dipole interaction respectively, the magnons are driven directly by a strong microwave field simultaneously. Frist, the intensity of driving magnetic field which can reach the threshold condition of phonon laser is given. Then, we demonstrate that the adjustable external magnetic field can be used as a good control method to the phonon laser. Compared with phonon laser in optomechanical systems, our scheme brings a new degree of freedom of manipulation. Finally, with the experimentally feasible parameters, threshold power in our scheme is close to the case of optomechanical systems. Our study may inspire the field of magnetically controlled phonon lasers.

“…Very recently, the parametric drive has been used to enhance the nonlinear coupling [29][30][31][32][33][34] in some systems. By exploiting coupled cavities, many applications have been studied, such as single-photon generation [35], steady-state entanglement [36], thermal phonon squeezing [37], and phonon laser [38]. In the study of phononic devices [39][40][41], the phonon laser [42][43][44][45] plays a key role in integrating coherent phonon sources, detectors, and waveguides [46].…”

A phase-controlled ultralow-threshold phonon laser is proposed by using tunable optical amplifiers in coupled-cavity-optomechanical system. The multiplicative behavior of the individual enhancements, by engineering the phases and strengths of external parametric driving, makes it possible to achieve the strong-coupling regime of optomechanics, where the switching among radiation-pressure, parametric amplification, and three-mode optomechanical couplings can be realized and ultralowthreshold phonon lasing is observable. This opens up novel prospects for applications in, e.g. quantum acoustics, nonlinear phonon devices, and ultrasensitive motion sensing.
