“…Cavity optomechanics is a rapidly developing research area for exploring the radiation-pressure-mediated interaction between photons and mechanical systems [27][28][29][30][31][32][33][34][35]. In the view of these important results, it is natural to investigate the magnon-phonon interaction in YIG spheres and their quantum characteristics.…”

Quantum manipulation of mechanical resonators has been widely applied in fundamental physics and quantum information processing. Among them, cooling the mechanical system to its quantum ground state is regarded as a key step. In this work, we propose a scheme which one can realize ground-state cooling of resonator in a cavity magnomechanical system. The system consists of a microwave cavity and a small ferromagnetic sphere, in which phonon-magnon coupling and cavity photon-magnon coupling can be achieved via magnetostrictive interaction and magnetic dipole interaction, respectively. After adiabatically eliminating the cavity mode, an effective Hamiltonian which consists of magnon and mechanical modes is obtained. Within experimentally feasible parameters, we demonstrate that the ground-state cooling of the magnomechanical resonator can be achieved by extra magnetic damping. Unlike optomechanical cooling, magnomechanical interaction is utilized to realize the cooling of resonators. We further illustrate the ground-state cooling can be effectively controlled by the external magnetic field.

“…In addition, the electromagnetic field (optical part) of the cavity optomechanical system is also affected by the motion of the mechanical resonator. Some researches have attracted significant attention, such as the optomechanically induced transparency [29][30][31], normal-mode splitting [32], photon blockade [33][34][35][36][37][38][39], etc. Of these studies, the photon blockade is a particularly important nonclassical light statistic effect and can be used to generate the single photon source for those fundamental studies in quantum information processing and quantum optics fields.…”

“…The first physical mechanism for achieving blockade has been studied theoretically [40][41][42][43][44] and realized experimentally in various systems [45][46][47]. Besides, due to the nonlinear optomechanical interaction, the optomechanical systems can also be used to achieve the photon blockade effect [33][34][35][36][37][38][39]. However, it is worth noting that the study of photon blockade in an optomechanical system requires the strong optomechanical coupling condition, which still poses major technological challenges.…”

Distinguishing photon blockade in a PT -symmetric optomechanical system

We study the effects of parity-time(PT )-symmetry on the photon blockade and distinguish the different blockade mechanisms in a double-cavity optomechanical system. By studying the light statistics of the system, we find the completely different photon blockade behaviors when the PTsymmetry is broken or unbroken, which is related to the PT phase transition. Furthermore, an interesting phenomenon that the two cavities are blocked at the same time is found with the appropriate system parameters. Those statistical phenomenons are all analyzed in detail and demonstrated by analytically solving the Schrödinger equation and numerically simulating the master equation, respectively. Finally, we also consider the non-PT symmetric situations which further reveal the physical essence of the photon blockade by comparing those results. Different from the usual photon blockade, our proposal is feasible even with weak parameter mechanism, i.e., the proposal neither requires the strong optomechanical coupling nor the large tunneling coupling between cavities.

“…The optomechanical interactions between the photons and the mechanical oscillation are at the heart of the field of cavity optomechanics [1][2][3][4]. Typically, there are two kinds of optomechanical interactions: the linear (i.e., the radiation-pressure-type) optomechanical coupling [5][6][7][8][9][10][11][12][13] and the quadratic optomechanical coupling [14][15][16][17][18][19][20][21]. In the two cases, the optomechanical couplings depend linearly and quadratically on the mechanical displacement, respectively.…”

We study the spectrum of single-photon emission and scattering in a mixed optomechanical model which consists of both linear and quadratic optomechanical interactions. The spectra are calculated based on the exact long-time solutions of the single-photon emission and scattering processes in this system. We find that there exist some phonon sideband peaks in the spectra and there are some sub peaks around the phonon sideband peaks under proper parameter conditions. The correspondence between the spectral features and the optomechanical interactions is confirmed, and the optomechanical coupling strengths can be inferred by analyzing the resonance peaks and dips in the spectra.
