论文摘要
我们概括了狄拉克 - 布洛克方程的通常框架，用于计算由空间均匀的光脉冲激发的2D材料的非线性光学响应，以与结构化的光脉冲。对于石墨烯样材料的情况，我们在存在空间不均匀场的情况下得出了Dirac-Bloch方程的一般形式。然后，作为我们方法应用的示例，我们明确考虑携带光脉冲与石墨烯相互作用的角动量的情况。
We generalise the usual framework of Dirac-Bloch equations, used to compute the nonlinear optical response of 2D materials excited by spatially uniform optical pulses, to the case of structured light pulses. We derive the general form of Dirac-Bloch equations in the presence of a spatially inhomogeneous field, for the case of a graphene-like material. Then, as as example of application of our method, we consider explicitly the case of angular momentum carrying optical pulses interacting with graphene.
