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…
Tailoring tricolor structure of magnetic topological insulator for robust axion insulator
M. Mogi, M. Kawamura, A. Tsukazaki +4
Exploration of novel electromagnetic phenomena is a subject of great interest in topological quantum materials. One of the unprecedented effects to be experimentally verified is to…
Current-driven instability of quantum anomalous Hall effect in ferromagnetic topological insulators
Minoru Kawamura, Ryutaro Yoshimi, Atsushi Tsukazaki +3
Instability of quantum anomalous Hall (QAH) effect has been studied as function of electric current and temperature in ferromagnetic topological insulator thin films. We find that…
