Controlling the Polarization and Vortex Charge of $γ$ Photons via Nonlinear Compton Scattering

Author(s): Jing-Jing Jiang, Kai-Hong Zhuang, Jia-Ding Chen, Jian-Xing Li, and Yue-Yue Chen High-energy vortex $γ$ photons have significant applications in many fields. However, their generation and angular momentum manipulation are still great challenges. Here, we first investigated the generation of vortex $γ$ photons with controllable spin and orbital angular momenta via nonlinear Compt… [Phys. Rev. Lett. 134, 153802] Published Thu Apr 17, 2025
