Spin-orbit torque on nuclear spins exerted by a spin accumulation via hyperfine interactions
Adam B. Cahaya, Alejandro O. Leon, Mohammad H. Fauzi
Spin-transfer and spin-orbit torques allow controlling magnetic degrees of freedom in various materials and devices. However, while the transfer of angular momenta between electron…
Synthesizing resistance plateau at the first Landau level confined in a quantum point contact
M. H. Fauzi, K. Nakagawara, K. Hashimoto +2
A comprehensive understanding of quantum Hall edge transmission, especially the hole-conjugate of a Laughlin state such as a state, is critical for advancing fundamental quan…
Hyperfine-mediated transport in a one-dimensional channel
M. H. Fauzi, Y. Hirayama
We survey some recent accumulated body of works on hyperfine-mediated transport in a confined one-dimensional channel, realized typically by electrostatic gating. Our review begins…
Even-denominator fractional quantum Hall state in conventional triple-gated quantum point contact
Yasuaki Hayafuchi, Ryota Konno, Annisa Noorhidayati +4
The even-denominator states have attracted considerable attention owing to their possible applications in future quantum technologies. In this letter, we first report a 3/2 diagona…
Double Nuclear Spin Relaxation in Hybrid Quantum Hall Systems
M. H. Fauzi, William J. Munro, Kae Nemoto +1
Recent advances in quantum engineering have given us the ability to design hybrid systems with novel properties normally not present in the regime they operate in. The coupling of…
The quest and hope of Majorana zero modes in topological superconductor for fault-tolerant quantum computing: an introductory overview
Nur R. Ayukaryana, Mohammad H. Fauzi, Eddwi H. Hasdeo
Ettore Majorana, in his short life, unintendedly has uncovered the most profound problem in quantum computation by his discovery of Majorana fermion, a particle which is its own an…
Probing strain modulation in a gate-defined one dimensional electron system
M. H. Fauzi, M. F. Sahdan, M. Takahashi +5
Gate patterning on semiconductors is routinely used to electrostatically restrict electron movement into reduced dimensions. At cryogenic temperatures, where most studies are carri…
Dynamic nuclear polarization at high Landau levels in a quantum point contact
M. H. Fauzi, A. Noorhidayati, M. F. Sahdan +3
We demonstrate a way to polarize and detect nuclear spin in a gate-defined quantum point contact operating at high Landau levels. Resistively-detected Nuclear Magnetic Resonance (R…
Resistively-detected NMR lineshapes in a quasi-one dimensional electron system
M. H. Fauzi, A. Singha, M. F. Sahdan +5
We observe variation in the resistively-detected nuclear magnetic resonance (RDNMR) lineshapes in quantum Hall breakdown. The breakdown is locally occurred in a gate-defined quantu…
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…
Dicke Model for Quantum Hall Systems
Y. Hama, M. H. Fauzi, K. Nemoto +2
Quantum Hall (QH) systems consist of many-body electron and nuclear spins. They are coupled so weakly through the hyperfine interaction that normally electron spin dynamics are sca…
Nuclear Magnetometry Study of Spin Dynamics in Bilayer Quantum Hall Systems
M. H. Fauzi, S. Watanabe, Y. Hirayama
We performed a nuclear magnetometry study on quantum Hall ferromagnet with a bilayer total filling factor of . We found not only a rapid nuclear relaxation but al…
