Merging of Dirac points in a two-dimensional crystal
G. Montambaux, F. Piechon, J. -N. Fuchs +1
We study under which general conditions a pair of Dirac points in the electronic spectrum of a two-dimensional crystal may merge into a single one. The merging signals a topologica…
Electric-field-induced lifting of the valley degeneracy in alpha-(BEDT-TTF)_2I_3 Dirac-like Landau levels
M. O. Goerbig, J. -N. Fuchs, G. Montambaux +1
The relativistic Landau levels in the layered organic material alpha-(BEDT-TTF)_2I_3 [BEDT-TTF=bis(ethylenedithio)tetrathiafulvalene] are sensitive to the tilt of the Dirac cones,…
A new magnetic field dependence of Landau levels on a graphene like structure
Petra Dietl, Frederic Piechon, Gilles Montambaux
We consider a tight-binding model on the honeycomb lattice in a magnetic field. For special values of the hopping integrals, the dispersion relation is linear in one direction and…
