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，我们得到的强度的分析和数值估计。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。DOI：10.1103/PhysRevB.86.245411
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. DOI: 10.1103/PhysRevB.86.245411
