On the effect of weak disorder on the density of states in graphene
B. Dóra, K. Ziegler, P. Thalmeier
The effect of weak potential and bond disorder on the density of states of graphene is studied. By comparing the self-consistent non-crossing approximation on the honeycomb lattice…
Spin gap and Luttinger liquid description of the NMR relaxation in carbon nanotubes
Balázs Dóra, Miklós Gulácsi, Ferenc Simon +1
Recent NMR experiments by Singer et al. [Singer et al. Phys. Rev. Lett. 95, 236403 (2005).] showed a deviation from Fermi-liquid behavior in carbon nanotubes with an energy gap evi…
Local density of states and Friedel oscillations around a non-magnetic impurity in unconventional density wave
Andras Vanyolos, Balazs Dora, Attila Virosztek
We present a mean-field theoretical study on the effect of a single non-magnetic impurity in quasi-one dimensional unconventional density wave. The local scattering potential is tr…
