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…
