Multimode oscillation and its route to chaos in transverse-mode-coupled optomechanical resonators
Motoki Asano, Lalit Maharjan, Hiroshi Yamaguchi
Nonlinear oscillators exhibit rich collective phenomena including synchronization, bifurcation, and chaos. Experimentally accessing multimode nonlinear dynamics, however, remains c…
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…
