H. Ochoa, A. H. Castro Neto, V. I. Fal'ko, F. Guinea

摘要:

我们分析了石墨烯中自旋和声子之间的耦合。我们提出了一个完整的分析自旋和弯曲,平面外,振动之间可能的耦合。从紧束缚模型,我们得到的分析和数值估计的强度。我们发现,动力学效应,量子和热涨落引起的,显着提高自旋轨道间隙。

英文摘要:

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.
