Direct observation of the transverse near field of an edge excitation in a fractional quantum Hall state
Yunhyeon Jeong, Akinori Kamiyama, John N. Moore +6
Stroboscopic time-resolved photoluminescence (PL) microscopy and spectroscopy reveal that an electrically launched edge excitation in a fractional quantum Hall (FQH) state…
Spatiotemporal imaging of gate-controlled multipath dynamics of fractional quantum Hall edge excitations
Yunhyeon Jeong, Akinori Kamiyama, John N. Moore +6
Quantum Hall edge excitations, whose low-energy behavior admits a chiral conformal-field-theory description, are a promising platform for engineered dynamical experiments, includin…
Electrically induced bulk and edge excitations in the fractional quantum Hall regime
Quentin France, Yunhyeon Jeong, Akinori Kamiyama +4
We apply a voltage pulse to electrically excite the incompressible region of a two-dimensional electron liquid in the fractional quantum Hall state and investigate the coll…
Enhancing Spin Diffusion in GaAs Quantum Wells: The Role of Electron Density and Channel Width
B. W. Grobecker, A. V. Poshakinskiy, S. Anghel +3
This study explores the relationship between spin diffusion, spin lifetime, electron density and lateral spatial confinement in two-dimensional electron gases hosted in GaAs quantu…
Dynamics of the fractional quantum Hall edge probed by stroboscope measurements of trions
Akinori Kamiyama, Masahiro Matsuura, John N. Moore +3
By using observations from pump-probe stroboscopic confocal microscopy and spectroscopy, we demonstrate the dynamics of trions and the fractional quantum Hall edge on the order of…
Thermal Transport Imaging in the Quantum Hall Edge Channel
J. N. Moore, A. Kamiyama, T. Mano +1
Research focused on heat transport in the quantum Hall (QH) edge channel has successfully addressed fundamental theoretical questions surrounding the QH physics. However, the pictu…
