Pseudospin in optical and transport properties of graphene
arXiv:1105.0580 · doi:10.1103/PhysRevLett.107.156801
Abstract
We show that the pseudospin being an additional degree of freedom for carriers in graphene can be efficiently controlled by means of the electron-electron interactions which, in turn, can be manipulated by changing the substrate. In particular, an out-of-plane pseudospin component can occur leading to a zero-field Hall current as well as to polarization-sensitive interband optical absorption.
