Spin dynamics of a quasi-one-dimensional electron in the quantum limit
M. H. Fauzi, M. Takahashi, T. Aono +2
We study electron spin dynamics whose movement is restricted to the lowest one dimensional subband channel (), through nuclear spin relaxation rate measurement ($1/T…
Five and three quantum dot systems as apparatuses for measuring energy-levels
Tetsufumi Tanamoto, Tomosuke Aono
A quantum dot (QD) system provides various quantum physics of nanostructures. So far, many types of semiconductor QD structures have been fabricated and investigated experimentally…
Dipole-like dynamical nuclear spin polarization around a quantum point contact
Peter Stano, Tomosuke Aono, Minoru Kawamura
We theoretically investigate the dynamical nuclear spin polarization in a quantum point contact (QPC) at finite magnetic field. We find that when the QPC is tuned to be spin select…
Tight-binding theory of surface spin states on bismuth thin films
Kazuo Saito, Hirokatsu Sawahata, Takashi Komine +1
The surface spin states for bismuth thin films were investigated using an tight-binding model. The model explains the experimental observations using angle-resolved photoemi…
Transport properties for a quantum dot coupled to normal leads with pseudogap
Bunpei Hara, Akihisa Koga, Tomosuke Aono
We study transport properties for a quantum dot coupled to normal leads with a pseudogap density of states at zero temperature, using the second-order perturbation theory based on…
Electronic magnetization of a quantum point contact measured by nuclear magnetic resonance
Minoru Kawamura, Keiji Ono, Peter Stano +2
We report an electronic magnetization measurement of a quantum point contact (QPC) based on nuclear magnetic resonance (NMR) spectroscopy. We find that NMR signals can be detected…
