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…
Signatures of correlated defects in an ultra-clean Wigner crystal in the extreme quantum limit
P. T. Madathil, C. Wang, S. K. Singh +8
Low-disorder two-dimensional electron systems in the presence of a strong, perpendicular magnetic field terminate at very small Landau level filling factors in a Wigner crystal (WC…
Ultraclean two-dimensional hole systems with mobilities exceeding 10 cm/Vs
Adbhut Gupta, C. Wang, S. K. Singh +4
Owing to their large effective mass, strong and tunable spin-orbit coupling, and complex band-structure, two-dimensional hole systems (2DHSs) in GaAs quantum wells provide rich pla…
Fractional Quantum Hall State at Filling Factor in Ultra-High-Quality GaAs 2D Hole Systems
Chengyu Wang, A. Gupta, S. K. Singh +6
Single-component fractional quantum Hall states (FQHSs) at even-denominator filling factors may host non-Abelian quasiparticles that are considered to be building blocks of topolog…
Valley-tunable, even-denominator fractional quantum Hall state in the lowest Landau level of an anisotropic system
Md. Shafayat Hossain, M. K. Ma, Y. J. Chung +7
Fractional quantum Hall states (FQHSs) at even-denominator Landau level filling factors () are of prime interest as they are predicted to host exotic, topological states of matt…
Record-quality GaAs two-dimensional hole systems
Yoon Jang Chung, C. Wang, S. K. Singh +6
The complex band structure, large spin-orbit induced band splitting, and heavy effective mass of two-dimensional (2D) hole systems hosted in GaAs quantum wells render them rich pla…
