Unusual hyperfine interaction of Dirac electrons and NMR spectroscopy in graphene
Balázs Dóra, Ferenc Simon
Theory of nuclear magnetic resonance (NMR) in graphene is presented. The canonical form of the electron-nucleus hyperfine interaction is strongly modified by the linear electronic…
Electron spin dynamics in strongly correlated metals
Balázs Dóra, Ferenc Simon
The temperature dependence of the electron spin life-time, T_1 and the g-factor are anomalous in alkali fullerides (K,Rb)_3C_60, which cannot be explained by the canonical Elliott-…
Generalized Elliott-Yafet theory of electron spin relaxation in metals: the origin of the anomalous electron spin life-time in MgB2
F. Simon, B. Dora, F. Muranyi +6
The temperature dependence of the electron spin relaxation time in MgB2 is anomalous as it does not follow the temperature dependence of the resistivity above 150 K, it has a maxim…
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…
