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…
Optomechanical parametric control of mid-infrared photons via molecular vibrational polariton
Ryoko Sakuma, Koji Sakai, Hajime Okamoto +2
Controlling mid-infrared (MIR) photons using well-developed telecom photonic platforms would enable new functionalities in molecular and quantum photonics. However, establishing ef…
Topological phase dynamics described by overtone-synthesized classical and quantum Adler equations
Hiroshi Yamaguchi, Motoki Asano
The Adler equation is a well-known one-dimensional model describing phase locking and synchronization. Motivated by recent experiments using optomechanical oscillators, we extend t…
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…
