Wakefield-Dressed Relativistic Vortex Electrons in Plasma Accelerators
Zhigang Bu, Lingang Zhang, Liangliang Ji
Plasma wakefield acceleration is usually regarded as a classical mechanism for producing high- energy charged-particle beams. Here we show that an axisymmetric plasma wakefield can…
PIC: A callback-centric particle-in-cell framework
Xuesong Geng, Yunwei Cui, Lingang Zhang +1
We present PIC, a Python-based electromagnetic particle-in-cell framework built around a callback-centric architecture. Existing PIC codes typically tie high performance to stat…
Super light-by-light scattering in vacuum induced by intense vortex lasers
Zhigang Bu, Lingang Zhang, Shiyu Liu +4
Collision of ultra-intense optical laser and X-ray free electron laser (XFEL) pulses is a promising approach to detecting nonlinear vacuum polarization (VP), a long-standing predic…
Compact Petawatt-Class Laser Wakefield Acceleration with Plasma Telescope
Xuesong Geng, Liangliang Ji, Baifei Shen
The compactness of laser wakefield acceleration (LWFA) is limited by its long focal length for high power lasers, e.g., more than 10 meters for 1-peatawatt (PW) laser pulse and up…
A spin-filter for polarized electron acceleration in plasma wakefields
Yitong Wu, Liangliang Ji, Xuesong Geng +7
We propose a filter method to generate electron beams of high polarization from bubble and blow-out wakefield accelerators. The mechanism is based on the idea to identify all elect…
Driving positron beam acceleration with coherent transition radiation
Zhangli Xu, Longqing Yi, Baifei Shen +6
Positron acceleration in plasma wakefield faces significant challenges since the positron beam must be pre-generated and precisely coupled into the wakefield, and most critically,…

Xuan Zhang, Tie-Jun Wang, Hao Guo +9
Polarization dependence on clamping intensity inside femtosecond filament was experimentally measured in air. By tuning the laser pulse ellipse from linear polarization to circular…
