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…
Transfer of spin to orbital angular momentum in the Bethe-Heitler process
Shaohu Lei, Shiyu Liu, Weiqing Wang +3
According to the conservation of angular momentum, when a plane-wave polarized photon splits into a pair of electron-positron under the influence of the Coulomb field, the spin ang…
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…
Generation of relativistic positrons carrying intrinsic orbital angular momentum
Shaohu Lei, Zhigang Bu, Weiqing Wang +2
High energy positrons can be efficiently created through high-energy photons splitting into electron-positron pairs under the influence of the Coulomb field. Here we show that a ne…
Vortex Breit-Wheeler Electron-positron pair creation via vortex gamma-photons
Zhigang Bu, Liangliang Ji, Shaohu Lei +3
Particles in quantum vortex states (QVS) carrying definite orbital angular momenta (OAM) brings new perspectives in various fundamental interaction processes. When unique propertie…
Unruh effect and angular momentum correlation of Rindler particles
Zhigang Bu, Liangliang Ji, Baifei Shen
It is well known that the rotational motion does not induce Unruh effect, because the Minkowski vacuum coincides with the vacuum state defined by the pure rotating observers. Howev…
Axionlike-particle generation by laser-plasma interaction
Shan Huang, Baifei Shen, Zhigang Bu +3
The hypothetical axion and axion-like particles, feebly coupled with photon, have not yet been found in any experiment. With the improvement of laser technique, much stronger but s…
Generalizing the Sokolov-Ternov effect for radiative polarization in intense laser fields
X. S. Geng, Z. G. Bu, Y. T. Wu +7
A consistent description of the radiative polarization for relativistic electrons in intense laser fields is derived by generalizing the Sokolov-Ternov effect in general field stru…
Spin-to-Orbital Conversion of Angular Momentum in Harmonic Generation Driven by Intense Circularly Polarized Beam
Shasha Li, Xiaomei Zhang, Weifeng Gong +2
A new physical mechanism to achieve spin-to-orbital angular momentum conversion based on the interaction of an intense circularly polarized (CP) laser beam with a plane foil is pre…
Nonlinear theory of intense laser-plasma interactions modified by vacuum-polarization effects
Wenbo Chen, Zhigang Bu, Hehe Li +2
The classical nonlinear laser-plasma interaction theory is corrected. Given the effects of vacuum polarization (induced by extreme laser) as nonlinear media response, one-dimension…
