Phase Transition to Insulating State from Quantum Hall State by Current-Induced Nuclear Spin Polarization
Shibun Tsuda, Minh-Hai Nguyen, Daiju Terasawa +2
We investigate the resistance enhancement state (RES) where the magnetoresistance of the fractional quantum Hall state (FQHS) is increased with dynamic nuclear spin polari…
Interlayer Diffusion of Nuclear Spin Polarization in Quantum Hall States
Minh-Hai Nguyen, Shibun Tsuda, Daiju Terasawa +3
At the spin transition point of quantum Hall states, nuclear spins in a two-dimensional electron gas are polarized by an electric current. Using GaAs/AlGaAs double-quantum-…
Spin blocker made of semiconductor double quantum well using the Rashba effect
S. Souma, H. Mukai, M. Ogawa +5
We propose a lateral spin-blockade device that uses an InGaAs/InAlAs double quantum well (DQW), where the values of the Rashba spin-orbit parameter are opposite in sign…
Anisotropy of Magnetoresistance Hysteresis around the Quantum Hall State in Tilted Magnetic Field
K. Iwata, M. Morino, A. Fukuda +4
We present an anisotropy of the hysteretic transport around the spin transition point at Landau level filling factor in tilted magnetic field. When the direction of the in-…
Pseudospin Soliton in the Bilayer Quantum Hall State
A. Fukuda, D. Terasawa, M. Morino +6
We investigate a domain structure of pseudospins, a soliton lattice in the bilayer quantum Hall state at total Landau level filling factor , in a tilted magnetic field, where…
Modulation of bilayer quantum Hall states by tilted-field-induced subband-Landau-level coupling
N. Kumada, K. Iwata, K. Tagashira +4
We study effects of tilted magnetic fields on energy levels in a double-quantum-well (DQW) system, focusing on the coupling of subbands and Landau levels (LLs). The subband-LL coup…
