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 conducti…
Observation of a Stripe/nematic Phase of Composite Fermions
Chengyu Wang, Siddharth K. Singh, Chia-Tse Tai +4
Electronic stripe/nematic phases are fascinating strongly-correlated states characterized by spontaneous rotational symmetry breaking. In the quantum Hall regime, such phases typic…
Even-denominator fractional quantum Hall states with spontaneously broken rotational symmetry
Chengyu Wang, A. Gupta, S. K. Singh +5
The interplay between the fractional quantum Hall effect and nematicity is intriguing as it links emerging topological order and spontaneous symmetry breaking. Anisotropic fraction…
Density Dependence of the Phases of the Integer Quantum Hall Plateau in Low Disorder Electron Gases
Haoyun Huang, Waseem Hussain, S. A. Myers +3
Recent magnetotransport measurements in low-disorder electron systems confined to GaAs/AlGaAs samples revealed that the integer quantum Hall plateau is broken into three di…
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…
