Incompressible Even Denominator Fractional Quantum Hall States in the Zeroth Landau Level of Monolayer Graphene

Sujit Narayanan, Bitan Roy, Malcolm P. Kennett

Incompressible even denominator fractional quantum Hall states at fillings $\nu =\pm \frac{1}{2}$ and $\nu =\pm \frac{1}{4}$ have been recently observed in monolayer graphene. We use a…
