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…
Fractional quantum Hall state at with energy gap up to 6 K, and possible transition from one- to two-component state
Siddharth Kumar Singh, Chengyu Wang, Adbhut Gupta +3
The fractional quantum Hall state (FQHS) observed in the lowest Landau level at filling factor in wide quantum wells has been enigmatic for decades because the two-dimensio…
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…
Competing Many-Body Phases at Small Fillings in Ultrahigh-Quality GaAs 2D Hole Systems: Role of Landau Level Mixing
Chengyu Wang, A. Gupta, S. K. Singh +4
The fractional quantum Hall state (FQHS), an incompressible liquid state hosting anyonic excitations with fractional charge and statistics, represents a compelling many-body phase…
Developing fractional quantum Hall states at even-denominator fillings 1/6 and 1/8
Chengyu Wang, P. T. Madathil, S. K. Singh +5
In the extreme quantum limit, when the Landau level filling factor , the dominant electron-electron interaction in low-disorder two-dimensional electron systems leads to exoti…
