Spiral momentum spectra and spin asymmetry in vacuum pair production driven by phase-modulated elliptically polarized electric fields
Li-Yi Yang, Hong-Hao Fan, Jing-He Huang +2
We study vacuum electron--positron pair production in phase-modulated elliptically polarized electric fields using the quantum kinetic equations. We analyze how the modulation ampl…
Spin - resolved momentum distributions and vortex evolution in multiphoton pair production within a modified two-level model
Qi-Rong Wang, Hong-Hao Fan, Musajan Kadir +2
We investigate spin-resolved momentum distributions and phase vortices in multiphoton electron-positron pair production within a modified two-level model. This model retains the di…
High-charge, highly polarized positron beams generated from a laser-driven nanowire-array target
De-Sheng Zhang, Cui-Wen Zhang, Kun Xue +4
The generation of high-charge, highly polarized positron beams in the interaction of a linearly polarized laser pulse with a nanowire-array target is investigated. Here, laser-driv…
Polarization-resolved attosecond gamma-ray emission from few-cycle laser interactions with cone targets
De-Sheng Zhang, Cui-Wen Zhang, Xue-Ren Hong +3
Linearly polarized attosecond -ray pulses in the MeV range are generated from a cone target irradiated by a single few-cycle laser pulse. Electron layers are periodically extrac…

We carry out a six-parameter multi-objective Bayesian optimisation of a carbon--hydrogen double-layer target for target-normal-sheath proton acceleration. The campaign consists of…
Bayesian optimization of double-pulse temporal shaping for enhanced target-normal-sheath proton acceleration under fixed laser energy
Chengqi-Zhang, Yang He, Mamat Ali Bake +1
Splitting an ultrashort drive pulse into a weak leading pulse and a strong main pulse is known to raise the energy of protons accelerated by the target-normal-sheath-acceleration (…
A Surrogate Model for Proton Spectrum Prediction to Map Transitions in Laser-Ion Acceleration
