Abstract (English)

Graphene, a two-dimensional material consisting of carbon atoms arranged in a honeycomb lattice, has become famous for the evidence that its electronic structure approximately corresponds to the one of massless Dirac fermions. However, in order to correctly describe graphene, the spin, which plays an essential role in the physics of Dirac fermions, has to be replaced by the so-called pseudospin, ...


Translation of the abstract (German)

Graphen, ein zweidimensionales Material aus Kohlenstoffatomen, die in einem Bienenwabengitter angeordnet sind, ist durch den Nachweis berühmt geworden, dass seine elektronische Struktur näherungsweise der masseloser Dirac-Fermionen entspricht. Der Spin, der eine essentielle Rolle in der Physik von Dirac Fermionen spielt, muss jedoch, um Graphen korrekt zu beschreiben, durch den sog. Pseudospin ...
