Radiation-induced electron spin polarization in ultrarelativistic kinetic turbulence
Peng Liu, Karen Z. Hatsagortsyan, Christoph H. Keitel +1
Electron spin polarization in radiative plasmas with ultrarelativistic kinetic turbulence under highly magnetized conditions is investigated using particle-in-cell simulations. We…
Anomalous lepton acceleration in the radiation reaction dominated reflection regime
Xiaofei Shen, Yue-Yue Chen, Karen Z. Hatsagortsyan +1
Relativistic electrons colliding with intense counterpropagating laser pulses are expected to lose energy through radiation reaction. However, we reveal a counterintuitive regime w…
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…
Broadband coherent XUV light from microbunching in an intense laser pulse
Michael J. Quin, Antonino Di Piazza, Çağrı Erciyes +2
Attosecond pulses of coherent extreme ultraviolet (XUV) light are instrumental for investigating subatomic dynamics and can be produced using a free-electron laser (FEL). It has be…
Highly Polarized Energetic Electrons via Intense Laser-Irradiated Tailored Targets
Xiaofei Shen, Zheng Gong, Karen Z. Hatsagortsyan +1
A method for the generation of ultrarelativistic electron beams with high spin polarization is put forward, where a tightly-focused linearly-polarized ultraintense laser pulse inte…
Electron slingshot acceleration in relativistic preturbulent shocks explored via emitted photon polarization
Zheng Gong, Xiaofei Shen, Karen Z. Hatsagortsyan +1
Transient electron dynamics near the interface of counterstreaming plasmas at the onset of a relativistic collisionless shock (RCS) is investigated using particle-in-cell simulatio…
