Interlayer-correlated fractional quantum Hall state in a trilayer electron system
Chengyu Wang, C. T. Tai, N. Toemtrisna +4
In multilayer quantum Hall systems, when the layer separation is sufficiently small, the interplay between intralayer and interlayer Coulomb interactions can lead to exotic, multi-…
Engineering Quantum Criticality in the Integer Quantum Hall Regime through a Screening Layer
C. T. Tai, P. T. Madathil, A. Gupta +3
Disorder-induced localization of electrons and electron-electron interaction are among the most fundamental problems in condensed matter physics. In two-dimensional electron system…
Observation of e/4 charge at in GaAs
Tomer Alkalai, Emily Hajigeorgiou, Adbhut Gupta +9
Even-denominator fractional quantum Hall states (FQHSs) fall outside the standard Laughlin's and Jain's odd-denominator hierarchy. In this work, we study the FQHS in the lo…
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…
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…
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…
