Generation of Isolated Collimated Polarized -ray Beams via Spatiotemporal Optical Vortex Modulation
Xinyu Xie, Fengyu Sun, Huai-Hang Song +2
Attosecond, collimated, bright, polarized -ray sources are in high demand across nuclear physics, astrophysics, and high-energy physics. However, realizing attosecond duration,…
Detecting Linear Breit-Wheeler Signals with a Laser-Foil Setup
Huai-Hang Song, Wei-Min Wang, Yu-Tong Li +4
As a fundamental QED process, linear Breit-Wheeler (LBW) pair production predicted 90 years ago has not yet been demonstrated in experiments with real photons. Here, we propose an…
Photon-polarization-resolved linear Breit-Wheeler pair production in a laser-plasma system
Huai-Hang Song, Zheng-Ming Sheng
The linear Breit-Wheeler (LBW) process, mediated by photon-photon collisions, can emerge as the dominant pair production mechanism in the ultraintense laser-plasma interaction for…
From linear to nonlinear Breit-Wheeler pair production in laser-solid interactions
Huai-Hang Song, Wei-Min Wang, Min Chen +1
During the ultraintense laser interaction with solids (overdense plasmas), the competition between two possible quantum electrodynamics (QED) mechanisms responsible for pai…
Dense Polarized Positrons from Laser-Irradiated Foil Targets in the QED Regime
Huai-Hang Song, Wei-Min Wang, Yu-Tong Li
Dense positrons are shown to be effectively generated from laser-solid interactions in the strong-field quantum electrodynamics (QED) regime. Whether these positrons are polarized…
YUNIC: A Multi-Dimensional Particle-In-Cell Code for Laser-Plasma Interaction
Huai-Hang Song, Wei-Min Wang, Yu-Tong Li
For simulating laser-plasma interactions, we developed a parallel, multi-dimensional, fully relativistically particle-in-cell (PIC) code, named YUNIC. The core algorithm is introdu…
Spin and polarization effects on the nonlinear Breit-Wheeler pair production in laser-plasma interaction
Huai-Hang Song, Wei-Min Wang, Yan-Fei Li +5
The spin effect of electrons/positrons (/) and polarization effect of photons are investigated in the interaction of two counter-propagating linearly polarized 10-PW-…
Low-frequency whistler waves excited by relativistic laser pulses
Huai-Hang Song, Wei-Min Wang, Jia-Qi Wang +2
It is shown by multi-dimensional particle-in-cell simulations that intense secondary whistler waves with special vortex-like field topology can be excited by a relativistic laser p…
Spin-polarization effects of an ultrarelativistic electron beam in an ultraintense two-color laser pulse
Huai-Hang Song, Wei-Min Wang, Jian-Xing Li +2
Spin-polarization effects of an ultrarelativistic electron beam head-on colliding with an ultraintense two-color laser pulse are investigated comprehensively in the quantum radiati…
