Uniquely identifying quantum Hall phases in charge neutral graphene
Jincheng An, Ganpathy Murthy
Charge-neutral graphene in the quantum Hall regime is an example of a quantum Hall ferromagnet in a complex spin-valley space. This system exhibits a plethora of phases, with the p…

Fractional quantum Hall coexistence phases in higher Landau levels of graphene
Jincheng An, Ajit C. Balram, Udit Khanna +1
Monolayer graphene under a strong magnetic field near charge neutrality manifests the integer and fractional quantum Hall effects. Since only some of the four spin/valley flavors a…

Magnon transmission across mono-layer graphene junction as a probe of electronic structure
Suman Jyoti De, Sumathi Rao, Ganpathy Murthy
We study magnon transmission across gate-controlled junctions in the manifold of Landau levels in monolayer graphene, in the presence of both spin and valley Zeeman fields. S…
