Nonreciprocal phonon propagation via spatially asymmetric magnon-phonon coupling
Hiroyuki Moriya, Motoki Asano, Daiki Hatanaka +3
Nonreciprocal propagation of surface acoustic waves (SAWs) based on the spatial asymmetry of magnon-phonon coupling is demonstrated. This nonreciprocity is enabled by an acoustic w…
Optically tunable nonlinear mechanical damping in an optomechanical resonator
Hideki Arahari, Motoki Asano, Hiroshi Yamaguchi +1
We theoretically propose and experimentally demonstrate optically tunable nonlinear mechanical damping in a cavity optomechanical system utilizing a partly resolved sideband regime…
On-chip magnon polaron generation in mode-matched cavity magnomechanics
Daiki Hatanaka, Motoki Asano, Megumi Kurosu +3
Generation of magnon polarons, which are hybridized states resulting from strong magnon-phonon coupling, is a key to enabling coherent manipulation in acoustic and spintronic devic…
Synthesized Kuramoto potential via optomechanical Floquet engineering
Motoki Asano, Hajime Okamoto, Hiroshi Yamaguchi
Synchronization is a ubiquitous scientific phenomenon in various physical systems. Here, we examine the feasibility of generating multistable and dynamically tunable synchronizatio…
A fiber-type optomechanical array using high-Q microbottle resonators
Motoki Asano, Hiroshi Yamaguchi, Hajime Okamoto
We demonstrate a fiber-type optomechanical array consisting of elastically interconnected silica microbottle resonators with high-Q optical and mechanical modes. In total, fifty op…
Evanescently coupled topological ring-waveguide systems for chip-scale ultrahigh frequency phononic circuits
Daiki Hatanaka, Hiroaki Takeshita, Motoki Kataoka +3
Topological phononics enabling backscattering-immune transport is expected to improve the performance of electromechanical systems for classical and quantum information technologie…
