Spin-orbit coupling assisted by flexural phonons in graphene    [PDF]

H. Ochoa, A. H. Castro Neto, V. I. Falko, F. Guinea

We analyze the couplings between spins and phonons in graphene. We present a complete analysis of the possible couplings between spins and flexural, out of plane, vibrations. From tight-binding models we obtain analytical and numerical estimates of their strength. We show that dynamical effects, induced by quantum and thermal fluctuations, significantly enhance the spin-orbit gap.
