SPIRE: Spin-Resolved Particle-in-Cell with Radiative Corrections for Extreme Laser--Plasma Interactions
Xian-Zhang Wu, Huai-Hang Song, Wei-Min Wang +1
We present SPIRE, a spin- and photon-polarization-resolved particle-in-cell (PIC) code for self-consistent simulations of laser-plasma interactions in the strong-field quantum elec…

Probing vacuum birefringence in an Ultrastrong Laser Field via High-energy Gamma-ray Polarimetry
Da-Lin Wang, Xian-Zhang Wu, Rui-Qi Qin +5
Vacuum birefringence (VB), a fundamental prediction of nonlinear quantum electrodynamics (QED), has eluded direct laboratory detection due to its extreme weakness. We propose a com…
