Landauer-Büttiker approach for hyperfine mediated electronic transport in the integer quantum Hall regime
Aniket Singha, M. H. Fauzi, Yoshiro Hirayama +1
The interplay of spin-polarized electronic edge states with the dynamics of the host nuclei in quantum Hall systems presents rich and non-trivial transport physics. Here, we develo…
Fabry-Pérot interference in a triple-gated quantum point contact
Shunta Maeda, Satoru Miyamoto, Mohammad H. Fauzi +3
We demonstrated that a triple-gated GaAs quantum point contact, which has an additional surface gate between a pair of split gates to strengthen the lateral confinement, produces t…
NMR Tracing of Hyperfine-Mediated Nuclear Spin Diffusion in Fractional Quantum Hall Domain Phases
S. Miyamoto, T. Hatano, S. Watanabe +1
We present an enhanced diffusion of nuclear spin polarization in fractional quantum Hall domain phases at . Resistively-detected NMR mediated by electrically driven domain-…
Localized NMR Mediated by Electrical-Field-Induced Domain Wall Oscillation in Quantum-Hall-Ferromagnet Nanowire
S. Miyamoto, T. Miura, S. Watanabe +2
We present fractional quantum Hall domain walls confined in a gate-defined wire structure. Our experiments utilize spatial oscillation of domain walls driven by radio frequency ele…
