Landau level splitting due to graphene superlattices
G. Pal, W. Apel, L. Schweitzer
The Landau level spectrum of graphene superlattices is studied using a tight-binding approach. We consider non-interacting particles moving on a hexagonal lattice with an additiona…

Scaling at chiral quantum critical points in two dimensions
L. Schweitzer, P. Markos
We study the localization properties of electrons moving on two-dimensional bi-partite lattices in the presence of disorder. The models investigated exhibit a chiral symmetry and b…

Logarithmic scaling of Lyapunov exponents in disordered chiral two-dimensional lattices
P. Markos, L. Schweitzer
We analyze the scaling behavior of the two smallest Lyapunov exponents for electrons propagating on two-dimensional lattices with energies within a very narrow interval around the…
