Relation between Zitterbewegung and the charge conductivity, Berry curvature and the Chern number of multi band systems
József Cserti, Gyula Dávid
We show that the charge conductivity for impurity free multi band electronic systems can be expressed in terms of the diagonal and non-diagonal elements of the Zitterbewegung ampli…

Trigonal warping and anisotropic band splitting in monolayer graphene due to Rashba spin-orbit coupling
Peter Rakyta, Andor Kormanyos, Jozsef Cserti
We study the electronic band structure of monolayer graphene when Rashba spin-orbit coupling is present. We show that if the Rashba spin-orbit coupling is stronger than the intrins…

Chiral currents in gold nanotubes
D. Zs. Manrique, J. Cserti, C. J. Lambert
Results are presented for the electron current in gold chiral nanotubes (AuNTs). Starting from the band structure of (4,3) and (5,3) AuNTs, we find that the magnitude of the chiral…
