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…
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…
Low-temperature environments for quantum computation and quantum simulation
Hailong Fu, Pengjie Wang, Zhenhai Hu +2
This review article summarizes the requirement of low temperature conditions in existing experimental approaches to quantum computation and quantum simulation.
Finite-thickness effect and spin polarization of the even-denominator fractional quantum Hall states
Pengjie Wang, Jian Sun, Hailong Fu +6
The spin-polarized even-denominator fractional quantum Hall (FQH) states in the second Landau level (LL), i.e. 5/2 and 7/2, may possess novel quasi-particle excitations obeying non…
Re-Symmetrizing the Broken Symmetry with Isotropic Hydrostatic Pressure
Ke Huang, Pengjie Wang, L. N. Pfeiffer +4
Recent progresses in condensed matter physics, such as graphene, topological insulator and Weyl semimetal, often origin from the specific topological symmetries of their lattice st…
Stability of the 5/2 Fractional Quantum Hall State in a Corbino Disc Sample with In-plane Electric Fields

We report low-temperature transport measurements in strained InAs/Ga0.68In0.32Sb quantum wells, which supports time-reversal symmetry-protected helical edge states. The temperature…
Stability of the bubble states in Corbino geometry under a tilted field
Pengjie Wang, Yijia Wu, Hua Chen +6
We measured the activation energy gap of the N = 2 bubble states using tilted-field technique in two GaAs/AlGaAs samples with Corbino geometry, and observed monotonically decreasin…
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…
Nonlinear Transport of Graphene in the Quantum Hall Regime
Shibing Tian, Pengjie Wang, Xin Liu +6
We have studied the breakdown of the integer quantum Hall (QH) effect with fully broken symmetry, in an ultra-high mobility graphene device sandwiched between two single crystal he…
