Journal ArticleDOI
Gate-controlled electromechanical backaction induced by a quantum dot.
TL;DR: Coupling is demonstrated in a hybrid device composed of a gate-defined quantum dot integrated into a piezoelectricity-based mechanical resonator enabling milli-Kelvin phonon states to be detected via charge fluctuations in the quantum dot.
Journal ArticleDOI
Replacement of group‐III atoms on the growing surface during migration‐enhanced epitaxy
TL;DR: In this article, an InAs monolayer is grown between GaAs layers using migrationenhanced epitaxy and surface chemical characteristics during growth are investigated by reflection high-energy electron diffraction.
Journal Article
Controllable Coupling between Flux Qubit and Nanomechanical Resonator
Journal ArticleDOI
Tetrazomine, a new antibiotic produced by an actinomycete strain. Taxonomy, fermentation, isolation and characterization.
Kenichi Suzuki,Tsutomu Sato,Moto Morioka,Koji Nagai,Abe Kenji,Hiroshi Yamaguchi,Takeshi Saito,Yukio Ohmi,Kiyoshi Susaki +8 more
TL;DR: A new antibacterial antibiotic tetrazomine was found from the fermentation broth of an actinomycete strain which was isolated from beach sand collected at Chichijima, Ogasawara Islands, Tokyo, Japan and exhibited broad antimicrobial activity against Gram-positive and Gram-negative bacteria in vitro.
Journal ArticleDOI
Dispersive and dissipative coupling in a micromechanical resonator embedded with a nanomechanical resonator
Imran Mahboob,N. Perrissin,Katsuhiko Nishiguchi,Daiki Hatanaka,Yuma Okazaki,Akira Fujiwara,Hiroshi Yamaguchi +6 more
TL;DR: In the limit of strong excitation for the nanomechanical resonator, the dissipation in the micromechanical resonator can be reduced, resulting in a quality factor of >3× 10(6), and the possibility of self-oscillations is suggested.
