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…
Magnetotransport Study of the Canted Antiferromagnetic Phase in Bilayer Quantum Hall State
A. Fukuda, A. Sawada, S. Kozumi +5
Magnetotransport properties are investigated in the bilayer quantum Hall state at the total filling factor . We measured the activation energy elaborately as a function of the…
Excitation spectrum of Bilayer Quantum Hall Systems
Yuichi Shimoda, Tatsuya Nakajima, Anju Sawada
Excitation spectra in bilayer quantum Hall systems at total Landau-level filling are studied by the Hartree-Fock-Bogoliubov approximation. The systems have the spin degrees o…
Phase Transitions in the Bilayer Quantum Hall Effect
N. Kumada, D. Terasawa, Y. Shimoda +6
We measured the magnetoresistance of bilayer quantum Hall (QH) effects at the fractional filling factor by changing the total electron density and the density difference be…
