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…
Topological phase transition between composite-fermion and Pfaffian daughter states near ν = 1/2 FQHS
Siddharth Kumar Singh, C. Wang, C. T. Tai +5
=1/2 is among the most enigmatic many-body phases in two-dimensional electron systems as it appears in the ground-state rather than an excited Landau level. It is observed in wi…
Delocalization and Universality of the Fractional Quantum Hall Plateau-to-Plateau Transitions
P. T. Madathil, K. A. Villegas Rosales, C. T. Tai +5
Disorder and electron-electron interaction play essential roles in the physics of electron systems in condensed matter. In two-dimensional, quantum Hall systems, extensive studies…
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…
Highly-Anisotropic Even-Denominator Fractional Quantum Hall State in an Orbitally-Coupled Half-Filled Landau Level
Chengyu Wang, A. Gupta, Y. J. Chung +5
The even-denominator fractional quantum Hall states (FQHSs) in half-filled Landau levels are generally believed to host non-Abelian quasiparticles and be of potential use in topolo…
