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…
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…
Topological surface states in the Kondo insulator YbB revealed via planar tunneling spectroscopy
A. Gupta, A. Weiser, L. H. Greene +8
Planar tunneling spectroscopy of the Kondo insulator SmB suggests that an interaction between the surface Dirac fermions and the bulk spin excitons results in incompletely prot…
