Observation of even-denominator fractional quantum Hall states at and 5/4 in the lowest Landau level
Siddharth Kumar Singh, Chengyu Wang, Adbhut Gupta +3
Two-dimensional electron systems (2DESs) confined to wide GaAs quantum wells provide a unique platform to study exotic fractional quantum Hall states (FQHSs) because the 2DES has a…
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…
Fractional quantum Hall state at with energy gap up to 6 K, and possible transition from one- to two-component state
Siddharth Kumar Singh, Chengyu Wang, Adbhut Gupta +3
The fractional quantum Hall state (FQHS) observed in the lowest Landau level at filling factor in wide quantum wells has been enigmatic for decades because the two-dimensio…
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…
