Chiral symmetry breaking and topological charge of graphene nanoribbons
Hyun Cheol Lee, S. -R. Eric Yang
We explore the edge properties of rectangular graphene nanoribbons featuring two zigzag edges and two armchair edges. Although the self-consistent Hartree-Fock fields break chiral…

Graphene nanosystems and low-dimensional Chern-Simons topological insulators
Y. H. Jeong, S. -R. Eric Yang
A graphene nanoribbon is a good candidate for a Chern-Simons topological insulator since it obeys particle-hole symmetry. We show that in a finite semiconducting armchair r…

Coulomb impurity problem of graphene in magnetic fields
S. C. Kim, S. -R. Eric Yang
Analytical solutions of the Coulomb impurity problem of graphene in the absence of a magnetic field show that when the dimensionless strength of the Coulomb potential reaches a…
