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…
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…
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…
Microwave-regime demonstration of plasmonic non-reciprocity in a flowing two-dimensional electron gas
Jingyee Chee, Han Sae Jung, Shannon Harvey +4
The speed of a plasmonic wave in the presence of electron drift in a conductor depends on the wave's propagation direction, with the wave traveling along the drift (`forward wave')…
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…
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…
3/2 Fractional Quantum Hall Plateau in Confined Two-Dimensional Electron Gas
Hailong Fu, Yijia Wu, Ruoxi Zhang +9
Even-denominator fractional quantum Hall (FQH) states, such as 5/2 and 7/2, have been well known in a two-dimensional electron gas (2DEG) for decades and are still investigated as…
Composite Fermions Waltz to the Tune of a Wigner Crystal
Yang Liu, H. Deng, M. Shayegan +3
When the kinetic energy of a collection of interacting two-dimensional (2D) electrons is quenched at very high magnetic fields so that the Coulomb repulsion dominates, the electron…
