Observation of even-denominator fractional quantum Hall states at $ν = 3/4$ 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 $ν = 1/2$ 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 $ν = 1/2$ in the lo…
