Symmetry of Model N = 3 for Graphene with Charged Pseudo-Excitons
Halina V. Grushevskaya, George Krylov, V. A. Gaisyonok and D. W. Serow

A model N = 3 of graphene charge carriers has been proposed. Within the model the pseudo-helicity is determined by the exchange interaction for pz-electrons. The symmetry properties of the model have been examined. It has been shown that the pseudo-helicity conservation law allows to explain experimental data on "moire" pattern and long spin relaxation time in graphene.


Key words: graphene monolayer, Dirac-Hartree-Fock self-consistent field, second quantized exchange interaction, charged pseudo-exciton, supperlattice
