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…
Generation-Resolved Signatures in QED Cascades: Diagnostics for Ultraintense Laser Parameters
Ke-Jia Wei, Feng Wan, Hao-Tian Wang +3
We present a generation-resolved analysis of shower-type, spin- and polarization-dependent quantum electrodynamics (QED) cascades initiated by head-on collisions of ultraintense la…
Generation of Polarized Overdense Pair-photon Fireball via Laser-Driven Nonlinear-linear QED Cascade
Zhen-Ke Dou, Qian Zhao, Feng Wan +3
Relativistic, polarized pair-photon fireballs are central to understand the microscopic energy transfer of high-energy astrophysical outflows, yet generating an overdense fireball…
Generating Cylindrical Vector γ Rays via Beam-Target Interactions: Towards Structured Light at High Energies
Yue Cao, Kun Xue, Si-Man Liu +8
Structured γ rays, particularly cylindrical vector γ rays, offer promising tools for sub-nuclear imaging and polarization-sensitive probes in fundamental research and application…
Generation of Ultrabrilliant Positron Beam via Superponderomotive Injection in Laser Wakefield Acceleration
Ting Sun, Zhen-Ke Dou, Ya-Qing Huang +3
Plasma-based acceleration of positrons attracts extensive interest owing to the ultrahigh accelerating gradient and ultrashort duration, while generating wakefield positron beam by…
Generation of Relativistic Structured Spin-Polarized Lepton Beams
Zhong-Peng Li, Yu Wang, Yousef I. Salamin +6
Relativistic structured spin-polarized (SSP) particle beams, characterized by polarization structures, are of critical importance in a wide range of applications, such as material…
