From: Unconventional fractional quantum Hall effect in bilayer graphene
Observation of FQHE at T = 0.25 K in bilayer suspended graphene, magneto-resistance R xx (blue curve) and R xy (black curve) at the lateral voltage −27 V, after experiment4. Shown in red is the fitting with the cyclotron braid group hierarchy (as in the upper part of Table 2) for mirror valence-band FQHE states, including \(\nu =-\frac{1}{2}\) (the mirror fraction to \(\nu =\frac{1}{2}\)).
