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 l…

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…
