Spin-Resolved Decay of Axion-Like Particles into Electron--Positron Pairs in Strong Electromagnetic Fields
Xiaodan Mao, Yue-Yue Chen, Pei-Lun He
The paper derives analytic spin‑resolved rates for the decay of an axion‑like particle into an electron‑positron pair in an intense laser field, showing how the ALP mass and the st…

Ultrafast Ionization Dynamics Encoded in a Photoelectron Spin Torus
Xiaodan Mao, Feng He, Pei-Lun He
We demonstrate that strong-field ionization of atoms in circularly polarized laser fields generates a photoelectron spin texture with toroidal topology in momentum space. Using tim…
