标题： Compton scattering of twisted light: angular distribution and polarization of scattered photons

摘要： 康普顿散射的扭曲光子在非相对论框架下使用一阶微扰理论进行研究。 我们用密度矩阵理论来表述这个问题，这使得能够通过利用系统的对称性，对扭曲粒子的散射过程获得新的见解。 特别是，我们分析了初始光束的参数，如发散角和轨道角动量的投影如何影响散射光子的角分布和偏振。 我们给出了初始扭曲光的康普顿散射光子的角分布和偏振的解析和数值结果，并将其与平面波光的标准情况进行了比较。 显示英文摘要

摘要： Compton scattering of twisted photons is investigated within a non-relativistic framework using first-order perturbation theory. We formulate the problem in the density matrix theory, which enables one to gain new insights into scattering processes of twisted particles by exploiting the symmetries of the system. In particular, we analyze how the angular distribution and polarization of the scattered photons are affected by the parameters of the initial beam such as the opening angle and the projection of orbital angular momentum. We present analytical and numerical results for the angular distribution and the polarization of Compton scattered photons for initially twisted light and compare them with the standard case of plane-wave light.
