Orbital Competition in Bilayer Graphene's Fractional Quantum Hall Effect
Bishoy M. Kousa, Nemin Wei, Allan H. MacDonald
The lowest Landau level of bilayer graphene has an octet of internal degrees of freedom, composed from spin, valley and orbital two-level systems. Dominance of orbitals over…

Partial condensation of mobile excitons in graphene multilayers
Igor V. Blinov, Chunli Huang, Nemin Wei +3
At a large displacement field, in rhomboedral and Bernal-stacked graphene a normal paramagnetic state transitions to a correlated state. Recent experiments showed that such systems…
