Quadrature skyrmions in two-dimensionally arrayed parametric resonators
Hiroshi Yamaguchi, Daiki Hatanaka, Motoki Asano
Skyrmions are topological solitons in two-dimensional systems and have been observed in various physical systems. Generating and controlling skyrmions in artificial resonator array…
Observation of Acoustically Induced Dressed States of Rare-Earth Ions
Ryuichi Ohta, Gregoire Lelu, Xuejun Xu +9
Acoustically induced dressed states of long-lived erbium ions in a crystal are demonstrated. These states are formed by rapid modulation of two-level systems via strain induced by…
Phononic-crystal cavity magnomechanics
Daiki Hatanaka, Motoki Asano, Hajime Okamoto +1
Establishing a way to control magnetic dynamics and elementary excitations (magnons) is crucial to fundamental physics and the search for novel phenomena and functions in magnetic…
Free-space optomechanical liquid probes using a twin-microbottle resonator
Motoki Asano, Hiroshi Yamaguchi, Hajime Okamoto
Cavity optomechanics provides high-performance sensor technology, and the scheme is also applicable to liquid samples for biological and rheological applications. However, previous…
A Kuramoto Network in a Single Nonlinear Microelectromechanical Device
Samer Houri, Motoki Asano, Hajime Okamoto +1
This work presents a frequency multiplexed 3-limit cycles network in a multimode microelectromechanical nonlinear resonator. The network is composed of libration limit cycles and b…
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…
