Quantum coherent negative bend resistance in InSb mesoscopic structures
N. Goel, T. Jayasekera, K. Mullen +4
Transport measurements were made on four-terminal devices fabricated from InSb/Al_xIn_(1-x)Sb quantum well structures at temperatures from 1.5 to 300K. Negative bend resistance, wh…
Electric-Field-Induced Nuclear Spin Resonance Mediated by Oscillating Electron Spin Domains in GaAs-Based Semiconductors
N. Kumada, T. Kamada, S. Miyashita +2
We demonstrate an alternative nuclear spin resonance using radio frequency (RF) electric field (nuclear electric resonance: NER) instead of magnetic field. The NER is based on the…
Decoherence of nuclear spins due to direct dipole-dipole interactions probed by resistively detected nuclear magnetic resonance
T. Ota, G. Yusa, N. Kumada +3
We study decoherence of nuclear spins in a GaAs quantum well structure using resistively detected nuclear magnetic resonance. The transverse decoherence time T2 of 75As nuclei is e…
Nuclear spin population and its control toward initialization using an all-electrical sub-micron scale nuclear magnetic resonance device
T. Ota, G. Yusa, N. Kumada +2
We study the nuclear spin population in a GaAs quantum well structure and demonstrate its initialization using an all-electrical nuclear magnetic resonance (NMR) device. In our dev…
Quantum Dynamics of Spin Wave Propagation Through Domain Walls
S. Yuan, H. De Raedt, S. Miyashita
Through numerical solution of the time-dependent Schrodinger equation, we demonstrate that magnetic chains with uniaxial anisotropy support stable structures, separating ferromagne…
Non-local Control of the Kondo Effect in a Double Quantum Dot-Quantum Wire Coupled System
S. Sasaki, S. Kang, K. Kitagawa +7
We have performed low-temperature transport measurements on a double quantum dot-quantum wire coupled device and demonstrated non-local control of the Kondo effect in one dot by ma…
