Successive Phase Transitions from a Composite Fermion Liquid to a Fractional Quantum Hall State at ν=3/2 Driven by In-Plane Magnetic Field
Xinghao Wang, L. N. Pfeiffer, A. Gupta +3
We report an even-denominator fractional quantum Hall state at ν = 3/2 induced entirely by in-plane magnetic field B_|| in an ultra-high-mobility GaAs quantum well. As B_|| increas…
Tailoring properties of Heusler alloys by elemental substitution and electron counting: (CoMn)FeGe, Co(FeMn)Ge, and (CoFe)MnGe
R. Mahat, S. Budhathoki, S. Regmi +6
Rational material design by elemental substitution is useful in tailoring materials to have desirable properties. Here we consider three non-equivalent substitutional series based…
Tunable multi-bit stochasticity in LaSrMnO-based probabilistic bits
I. Bhaduri, A. Jaman, W. Quiñonez +2
One promising approach to combat the rapidly escalating computational demands is to use networks of naturally stochastic units called probabilistic bits (p-bits). To date, hardware…
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…
Fractional quantum Hall valley ferromagnetism in the extreme quantum limit
Md. Shafayat Hossain, M. K. Ma, Y. J. Chung +7
Electrons' multiple quantum degrees of freedom can lead to rich physics, including a competition between various exotic ground states, as well as novel applications such as spintro…
Even-Denominator Fractional Quantum Hall State at Filling Factor ν = 3/4
Chengyu Wang, A. Gupta, S. K Singh +6
Fractional quantum Hall states (FQHSs) exemplify exotic phases of low-disorder two-dimensional (2D) electron systems when electron-electron interaction dominates over the thermal a…
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…
