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…
Demonstration of a Field-Effect Three-Terminal Electronic Device with an Electron Mobility Exceeding 40 Million cm^2/(Vs)
T. J. Martz-Oberlander, B. Bulgaru, Z. Berkson-Korenberg +6
We report the fabrication and operation of a source-drain-gate three-terminal field-effect electronic device with an electron mobility exceeding cm / (Vs). Seve…
Melting of quantum Hall Wigner and bubble crystals
H. Xia, Qianhui Xu, Jiasen Niu +7
A two-dimensional crystal melts via the proliferation and unbinding of topological defects, yet quantitatively predicting the melting temperature in real systems is challengi…
Topological Protection in a Landau Flat Band at , a Candidate Filling Factor for Unconventional Correlations
Waseem Hussain, Haoyun Huang, Loren N. Pfeiffer +3
Strong interactions in Landau flat bands are known to stabilize correlated states that do not form in other types of flat bands. We report hallmarks of topological protection at th…
Nonlinear transport of Wigner solid phase surrounding the two-flux composite fermion liquid
Yu-jiang Dong, Xinghao Wang, Jianmin Zheng +5
We have investigated the low temperature (T) transport properties of fractional quantum Hall (FQH) states in a high-mobility two-dimensional hole gas. According to the composite fe…
