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.
