Buckling-induced quadratic nonlinearity in silicon phonon waveguide structures
Megumi Kurosu, Daiki Hatanaka, Hajime Okamoto +1
We fabricated and characterized a single-crystal silicon phonon waveguide structure with lead zirconate titanate (PZT) piezoelectric transducers. The compressive stress in a silico…
Mode-sensitive magnetoelastic coupling in phononic-crystal magnomechanics
D. Hatanaka, H. Yamaguchi
Acoustically driven spin-wave resonance in a phononic crystal cavity is numerically investigated. The designed cavity enables confinement of gigahertz vibrations in a wavelength-sc…
The Librator: A new dynamical regime for nonlinear microelectromechanical devices
Samer Houri, Motoki Asano, Hajime Okamoto +1
We present a novel mode of operation for Duffing-type nonlinear microelectromechanical (MEMS) devices whereby a self-sustained multi-frequency output is generated. This new librato…
Cavity magnomechanics with surface acoustic waves
D. Hatanaka, M. Asano, H. Okamoto +3
Magnons, namely spin waves, are collective spin excitations in ferromagnets, and their control through coupling with other excitations is a key technology for future hybrid spintro…
Non-equilibrium quadratic measurement-feedback squeezing in a micromechanical resonator
Motoki Asano, Takuma Aihara, Tai Tsuchizawa +1
Measurement and feedback control of stochastic dynamics has been actively studied for not only stabilizing the system but also for generating additional entropy flows originating i…
Generation and propagation of topological solitons in a chain of coupled parametric-micromechanical-resonator arrays
Hiroshi Yamaguchi, Samer Houri
Using a coupled parametric-resonator array for generating and propagating a topological soliton in its rotating-frame phase space is theoretically and numerically investigated. In…
