“…In recent years, the analogous cavity magnomechanical system has received considerable attention [20,21]. It has been shown that cavity magnomechanics (CMM) has the potential to prepare macroscopic quantum states [22][23][24][25][26][27][28][29][30][31] and nonclassical states of microwave fields [32,33], and it has also promising applications in quantum information processing and quantum technologies [34][35][36][37][38][39][40][41][42][43]. In the CMM, a magnon mode (spin wave) couples to a deformation vibration mode of a ferromagnet (or ferrimagnet) via the magnetostrictive force, and to a microwave cavity mode via the magnetic dipole interaction.…”

Cavity magnomechanics has recently become a new platform for studying macroscopic quantum phenomena. The magnetostriction induced vibration mode of a large-size ferromagnet or ferrimagnet reaching its ground state represents a genuine macroscopic quantum state. Here we study the ground-state cooling of the mechanical vibration mode in a cavity magnomechanical system, and focus on the role of magnon squeezing in improving the cooling efficiency. We find that the magnon squeezing can significantly and even completely suppress the magnomechanical Stokes scattering. It thus becomes particularly useful in realizing ground-state cooling in the unresolved-sideband regime, where the conventional sideband cooling protocols become inefficient. We also find that the coupling to the microwave cavity plays only an adverse effect in mechanical cooling. This makes essentially the two-mode magnomechanical system (without involving the microwave cavity) a preferred system for cooling the mechanical motion, in which the magnon mode is established by a uniform bias magnetic field and a microwave drive field.

“…As an important part of quantum optomechanics, the cavity optomechanical system, which explores the radiation-pressure interaction between light fields and macroscopic mechanical resonators, is a rapidly developing research area in recent years and has attracted much attention due to the widespread applications in quantum information processing [9][10][11]. Due to the nonlinear optomechanical couplings, the cavity optomechanical system provides many alternative platforms for carrying out various interesting nonlinear phenomena, such as the generation of a squeezed state [12][13][14][15], cooling of mechanical resonator [10,[16][17][18][19], phonon (photon) blockade [20][21][22], quantum entanglement [23][24][25][26], normal mode splitting [27,28], nonreciprocal optical transmission [29,30], optomechanically induced transparency (OMIT) [31][32][33][34][35][36][37][38], and amplification (OMIA) [39][40][41][42], etc.…”

“…The performances of OMIT and OMIA processes are mainly described by the optical delay and transmission, which directly determine the storage time of information and the transfer efficiency of information, respectively. In recent years, the follow-up developments of OMIT and OMIA have been demonstrated in many schemes, such as multicavity OMIT [37,[51][52][53][54], hybrid OMIT [55,56], the two-phonon OMIT [57,58], OMIA in quadratically coupled optomechanical system [39], OMIA of atom-assisted cavity optomechanical system [40], optical amplification phenomenon in the system with mechanical gain [59], etc. Furthermore, the miscellaneous applications of OMIT has attracted a lot of attention, for instance, the fast-slow light [37,[60][61][62], the storage of light [61,63], the ultrasensitive measurements [64,65], etc.…”

We investigate the optical amplification of the output field and fast-slow light effect in a three-mode cavity optomechanical system without rotating wave approximation and discuss two ways of realizing the optical amplification effect. Resorting to the Coulomb coupling between the nanomechanical resonators, the asymmetric double optomechanically induced amplification effect can be achieved by utilizing the counterrotating term. Moreover, we find a remarkable optical amplification effect and observe the prominent fast-slow light effect at the singular point since the introduction of mechanical gain. Meanwhile, the transmission rate of the output field is increased by four orders of magnitude and the group delay time can reach in the order of 105μs. Our work is of great significance for the potential applications of optomechanically induced amplification in quantum information processing and quantum precision measurement.

“…This work was extended to reconfigurable nonreciprocal transmission between two microwave modes [21] and nonreciprocal enhancement of second-order sidebands [22]. In a cavity-magnon system that utilizes pathway interference, switching between fast and slow light transmission has been proposed [23] and experimentally achieved by tuning the relative phase of the magnon pumping and cavity probe [24]. Other important progress has been brought about by parity-time (PT )-symmetric photonic concepts that widen the * bulutay@fen.bilkent.edu.tr range of opportunities [25,26].…”

We study theoretically an optical cavity and a parity-time (PT )-symmetric pair of mechanical resonators, where all oscillators are pairwise coupled, forming an optomechanical system with a closed-contour interaction. Due to the presence of both gain and feedback, we explore its stability and the root loci over a wide coupling range. Under the red-sideband pumping and for the so-called PT -unbroken phase, it displays a double optomechanically induced transparency (OMIT) for an experimentally realizable parameter set. We show that both the transmission amplitude and the group delay can be continuously steered from the lower transmission window to the upper one by the loop coupling phase which breaks the time-reversal symmetry and introduces a static synthetic gauge field. In the PT -unbroken phase both the gain-bandwidth and delay-bandwidth products remain constant over the full range of the controlling phase. Tunability in transmission and bandwidth still prevails in the PT -broken phase, albeit over a reduced range. In essence, we suggest a simple scheme that grants coupling phase-dependent control of the single and double OMIT phenomena within an effective PT -symmetric optomechanical system.
