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…
Enhanced electron injection for efficient proton acceleration and neutron production in femtosecond laser-driven nano-structured targets
Yingzi Dai, Chengyu Qin, Hui Zhang +22
Micro- or nano-structured targets are advantageous in enhancing and manipulating laser-proton acceleration, due to the increased absorption of laser energy and onset of direct lase…
Collimated QED Cascades with Curved Plasma Mirror
Xuesong Geng, M. A. Serebryakov, E. N. Nerush +3
Converting light into matter has been a longstanding goal in physics, particularly the creation of electron-positron pairs through quantum electrodynamic (QED) processes. While cur…
Self-seeded photon acceleration by electron beam-driven transition radiation
Chaolu Ding, Xuesong Geng, Liangliang Ji
Photon acceleration (PA) driven by ultra-relativistic electron beams offers a promising approach to generating high-power, high-frequency coherent radiation sources. While current…
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…
Generation of Quantum Vortex Electrons with Intense Laser Pulses
Zhigang Bu, Liangliang Ji, Xuesong Geng +5
Accelerating a free electron to high energy forms the basis for studying particle and nuclear physics. Here it is shown that wavefunction of such an energetic electron can be furth…
