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…
Introducing Corrections to the Reflectance of Graphene by Light Emission
Ken-ichi Sasaki, Kenichi Hitachi, Masahiro Kamada +3
Monolayer graphene absorbs 2.3 percent of the incident visible light. This 'small' absorption has been used to emphasize the visual transparency of graphene, but it in fact means t…
Intrinsic and extrinsic origins of low-frequency noise in GaAs/AlGaAs Schottky-gated nanostructures
Kenichi Hitachi, Takeshi Ota, Koji Muraki
We study low-frequency noise in current passing through quantum point contacts fabricated from several GaAs/AlGaAs heterostructures with different layer structures and fabrication…
Observation of Hysteretic Transport Due to Dynamic Nuclear Spin Polarization in a GaAs Lateral Double Quantum Dot
Takashi Kobayashi, Kenichi Hitachi, Satoshi Sasaki +1
We report a new transport feature in a GaAs lateral double quantum dot that emerges only for magnetic field sweeps and shows hysteresis due to dynamic nuclear spin polarization (DN…
