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…

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…

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 col…
