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…
Classical-quantum gravity as quantum gravity in disguise
Masahiro Hotta, Sebastian Murk, Daniel R. Terno
Whether gravity must be quantized remains one of the biggest open problems in fundamental physics. Classical-quantum hybrid theories have recently attracted attention as a possible…
Exceeding the maximum classical energy density in fully charged quantum batteries
Masahiro Hotta, Kazuki Ikeda
Quantum batteries are anticipated to achieve significant advancements in energy storage capacity. In classical batteries, the energy density at each subsystem reaches its maximum v…
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…
