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-matter…
Laughlin pumping assisted by surface acoustic waves
Renfei Wang, Xiao Liu, Adbhut Gupta +8
The quantum Hall effect is a fascinating electrical transport phenomenon signified by precise quantization of Hall conductivity and vanishing longitudinal conductiv…
Observation of Quantized Charge Accumulation in a Quantum Anomalous Hall System
Yuanze Li, Jiahao Chen, Renfei Wang +6
The quantum anomalous Hall effect in magnetically doped topological insulators exhibits a quantized Hall conductance arising from the two-dimensional surface state…
Collective Pinning and Vortex Dynamics in type 2 superconducting thin films with Varying Magnetic Field
Yu Wu, Liangliang Guo, Renfei Wang +7
A perpendicular magnetic field penetrating a thin type-II superconductor slab produces vortices, with one vortex per flux quantum, h/2e. The vortices interact repulsively and form…
Anomalous acousto-current within the quantum Hall plateaus
Renfei Wang, Xiao Liu, Mengmeng Wu +7
We systematically study the acousto-current of two-dimensional electron systems in the integer and fractional quantum Hall regimes using surface acoustic waves. We are able to sepa…
Interaction between Surface Acoustic Wave and Quantum Hall Effects
Xiao Liu, Mengmeng Wu, Renfei Wang +6
Surface Acoustic Wave (SAW) is a powerful technique for investigating quantum phases appearing in two-dimensional electron systems. The electrons respond to the piezoelectric field…
