Topological Surface Charge Detection via Terahertz Time-domain Spectroscopy
Tong Shen, Yiyang Xie, Yucheng Dai +4
The topological magnetoelectric effect (TME) is a condensed-matter realization of the four-dimensional quantum Hall effect (4D-QHE), manifesting as quantized surface charge accumul…
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…
