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…
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…
Modified surface redshift of pulsars and magnetars by magnetized plasmas and vacuum polarization
Yuee Luo, Zhigang Bu, Wenbo Chen +2
The propagation of emissions in the relativistic streaming pair plasmas of pulsars and magnetars is studied within the framework of Gordon effective metric theory, and the effect o…
