Approaching Irrational Quantization
Zhihong Wu, Zhimou Chen, Siyuan Zhang +5
The integer and fractional quantum Hall effects reveal that quantized physical responses can take integer and fractional values, respectively. This naturally raises the question of…
Successive Phase Transitions from a Composite Fermion Liquid to a Fractional Quantum Hall State at ν=3/2 Driven by In-Plane Magnetic Field
Xinghao Wang, L. N. Pfeiffer, A. Gupta +3
We report an even-denominator fractional quantum Hall state at ν = 3/2 induced entirely by in-plane magnetic field B_|| in an ultra-high-mobility GaAs quantum well. As B_|| increas…
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…
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…
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…
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…
Thermal Activation Signatures of the Anderson Insulator and the Wigner Solid forming near
S. A. Myers, Haoyun Huang, Waseem Hussain +3
When interactions overcome disorder, integer quantum Hall plateaus support topological phases with different bulk insulators. In the center of the plateau the bulk is an Ande…
Two-dimensional hydrodynamic viscous electron flow in annular Corbino rings
Sujatha Vijayakrishnan, Z. Berkson-Korenberg, J. Mainville +5
The concept of fluidic viscosity is ubiquitous in our everyday life and for it to arise the fluidic medium must necessarily form a continuum where macroscopic properties can emerge…
Aharonov-Borm oscillation and Microwave-induced edge-magnetoplasmon modes enhanced by quantum point contact
Xinghao Wang, Wenfeng Zhang, L. N. Pfeiffer +2
AB oscillation in weak magnetic field (B<1.5kG) is observed in QPC due to interference between electrons propagating along different QPC channels. We also investigate photo-induced…
Topological protection revealed by real-time longitudinal and transverse studies
Anh Ho Hoai, Jian Huang, L. N. Pfeiffer +1
Topology provides an essential concept for achieving unchanged (or protected) quantum properties in the presence of perturbations. A challenge facing realistic applications is that…
Superballistic flow of viscous electron fluid induced by microwave irradiation in quantum point contact
Xinghao Wang, Wenfeng Zhang, Rui-Rui Du +3
We measure the resistance oscillation of quantum point contact (QPC) under microwave (MW) radiation. What is different from the common resistance oscillation induced by edge magnet…
Evidence for Topological Protection Derived from Six-Flux Composite Fermions
Haoyun Huang, Waseem Hussain, S. A. Myers +4
The composite fermion theory opened a new chapter in understanding many-body correlations through the formation of emergent particles. The formation of two-flux and four-flux compo…
Dynamic ordering transitions in charged solid
Jian Sun, Jiasen Niu, Yifan Li +5
The phenomenon of group motion is common in nature, ranging from the schools of fish, birds and insects, to avalanches, landslides and sand drift. If we treat objects as collective…
