Skyrmion Excitations in the Quantum Hall state in Monolayer Graphene
Jincheng An, Ajit C. Balram, Ganpathy Murthy
We investigate the skyrmion excited states atop the quantum Hall ferromagnetic ground state at filling factor in monolayer graphene. The competition among short-ran…

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…
