Skyrmion Excitations in the $\hat{I}½=-1$ Quantum Hall state in Monolayer Graphene

Jincheng An, Ajit C. Balram, Ganpathy Murthy

We investigate the skyrmion excited states atop the $SU(4)$ quantum Hall ferromagnetic ground state at filling factor $\hat{I}½=-1$ in monolayer graphene. The competition among short-ran…
