Graphene zigzag ribbons, square lattice models and quantum spin chains
Mahdi Zarea, Nancy Sandler
We present an extended study of finite-width zigzag graphene ribbons (ZGRs) based on a tight-binding model with hard-wall boundary conditions. We provide an exact analytic solution…

Quantum spin Hall phase in neutral zigzag graphene ribbons
Mahdi Zarea, Nancy Sandler
We present a detailed description of the nature of the wavefunction and spin distribution of the zero energy modes of zigzag graphene ribbons (ZGRs) in the presence of the intrinsi…

Landau level mixing by full spin-orbit interactions
Mahdi. Zarea, Sergio. E. Ulloa
We study a two-dimensional electron gas in a perpendicular magnetic field in the presence of both Rashba and Dresselhaus spin-orbit interactions. Using a Bogoliubov transformation…
