Spin-Resolved Decay of Axion-Like Particles into Electron--Positron Pairs in Strong Electromagnetic Fields
Xiaodan Mao, Yue-Yue Chen, Pei-Lun He
We investigate spin-resolved decay of an axion-like particle (ALP) into an electron--positron pair in an intense laser field. Using the Baier--Katkov quasiclassical operator formal…

Nonlinear Breit-Wheeler Process Driven by Intense Squeezed Light
Xin Ge, Kai-Hong Zhuang, Pei-Lun He +1
The nonlinear Breit-Wheeler process is a fundamental phenomenon of strong-field quantum electrodynamics and is usually studied for classically prescribed laser backgrounds. Here we…
