“…Furthermore, an important triple-resonance condition is possible, where the phonon frequency matches the difference in frequencies between the hybrid cavity-magnon modes [22], allowing selective cavity enhancement of scattering processes. This triple-resonance system has sparked significant interest, resulting in theoretical proposals for the generation of non-classical entangled states [23][24][25][26][27][28], squeezed states [29][30][31], classical and quantum information processing [32][33][34][35][36], quantum correlation thermometry [37], and exploring PT -symmetry [38][39][40][41]. Many of these proposals rely on the ability of the external drive to act on the mechanical motion, so called dynamical backaction.…”

Dynamical backaction resulting from radiation pressure forces in optomechanical systems has proven to be a versatile tool for manipulating mechanical vibrations. Notably, dynamical backaction has resulted in the cooling of a mechanical resonator to its ground-state, driving phonon lasing, the generation of entangled states, and observation of the optical-spring effect. In certain magnetic materials, mechanical vibrations can interact with magnetic excitations (magnons) via the magnetostrictive interaction, resulting in an analogous magnon-induced dynamical backaction. In this article, we directly observe the impact of magnon-induced dynamical backaction on a spherical magnetic sample's mechanical vibrations. Moreover, dynamical backaction effects play a crucial role in many recent theoretical proposals; thus, our work provides the foundation for future experimental work pursuing many of these theoretical proposals.

“…In this system, deformation modes in the YIG sphere are utilized as mechanical modes, and a magnon mode couples simultaneously with a microwave cavity mode and a phonon mode through magnetic-dipole interaction and magnetostrictive interaction, respectively. Such a platform of cavity magnomechanics, in analogy to cavity optomechanics, can further be used to explore a large diversity of effects, such as multipartite entanglement [59][60][61][62], controllable transmission [63][64][65], squeezed states [66,67], high-order sidebands [68,69], magnon nonlinearities [70,71], ground state cooling [72], quantum steering [73,74], exceptional points [75], and phonon lasering [76][77][78].…”

Generation and manipulation of phonon lasering in a two-drive cavity magnomechanical system

et al. 2023

A simple and feasible scheme for the generation and manipulation of phonon lasering is proposed and investigated based on a generic three-mode cavity magnomechanical system, in which a magnon mode couples simultaneously with a microwave cavity mode and a phonon mode. In sharp contrast to all previous phonon lasering schemes with only a single drive, the input pump field for the system in the proposed scheme is split into two microwave driving fields to drive the microwave cavity mode and the magnon mode, respectively. The impact of changing relative phase and relative amplitude ratio of the two microwave drives on mechanical gain, stimulated emitted phonon number, threshold power, and phonon emission line shape are theoretically and numerically investigated. The results indicate that the phonon laser action can be effectively controlled simply by adjusting the relative phase and relative amplitude ratio, so additional and tunable degrees of freedom are introduced to control the phonon laser. Considering the experimental feasibility of the generic cavity magnomechanical system and the two-drive approach, the present scheme provides a potentially practical route for the development of tunable phonon lasering devices with low-threshold, high-gain, and narrow-linewidth properties based on the platform of cavity magnomechanics.

Optomagnonically induced RoF chaotic synchronization

et al. 2022

View full text Add to dashboard Cite

Optomagnonics is a good platform for the interplay of radio frequency and optical signals, which are the primary communication carriers in the present day. On the basis of optomagnonics, we provide a multi-scale method for analyzing its behavior, including frequency comb and RoF chaotic synchronization at the microwave scale. Adjusting the pump light intensity permits the transition of RoF signals between harmonics, frequency combs, and chaotic movements. The dual optomagnonical device enables the synchronization of RoF signals between different cavities. Our study will contribute to the use of multiscale electromagnetic wave coupling in both conventional and quantum information applications.
