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…
