Cascade of fractional quantum Hall states in 2D system
Zhimou Chen, Jiaojie Yan, Yuxuan Zhu +11
The observation of the fractional quantum Hall (FQH) effect in 2D electron gases ushered in investigations of topological phases driven by strong electron correlations. Their remar…
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…
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…
A high-performance surface acoustic wave sensing technique
Mengmeng Wu, Xiao Liu, Renfei Wang +2
We present a superheterodyne-scheme demodulation system which can detect the amplitude and phaseshift of weak radio-frequency signals with extraordinarily high stability and resolu…
Probing quantum phases in ultra-high-mobility two-dimensional electron systems using surface acoustic waves
Mengmeng Wu, Xiao Liu, Renfei Wang +6
Transport measurement, which applies an electric field and studies the migration of charged particles, i.e. the current, is the most widely used technique in condensed matter studi…
