Topological Surface Charge Detection via Terahertz Time-domain Spectroscopy
Tong Shen, Yiyang Xie, Yucheng Dai +4
The topological magnetoelectric effect (TME) in three-dimensional topological insulators manifests as a quantized surface charge accumulation proportional to an applied magnetic fi…
Observation of Superfluidity and Meissner Effect of Composite Bosons in GaAs Quantum Hall System
Yuanze Li, Renfei Wang, Jiahao Chen +7
The quantum Hall effect (QHE) is theoretically understood as a superfluid condensate of composite bosons (CBs) -- bound states of electrons and magnetic flux quanta. While dissipat…
Topological Surface Charge Detection via Active Capacitive Compensation: A Pathway to the 4D Quantum Hall Effect
Yuanze Li, Renfei Wang, Yifan Zhang +6
The topological magnetoelectric effect (TME) in three-dimensional topological insulators (TIs), described by , serves as a condensed-matt…
Quantized Charge Accumulation in a Quantum Anomalous Hall System
Yuanze Li, Jiahao Chen, Renfei Wang +6
We report the first experimental observation of magnetic-field-induced quantized charge accumulation in a quantum anomalous Hall (QAH) system -- a phenomenon originating from the i…
Peregrine solitons and resonant radiation in cubic and quadratic media
Marcos Caso-Huerta, Lili Bu, Shihua Chen +2
We present the fascinating phenomena of resonant radiation emitted by transient rogue waves in cubic and quadratic nonlinear media, particularly those shed from Peregrine solitons,…
