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…
