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…
Unambiguous detection of high energy vortex states via the superkick effect
Zhengjiang Li, Shiyu Liu, Bei Liu +2
Vortex states of photons, electrons, and other particles are freely propagating wave packets with helicoidal wave fronts winding around the axis of a phase vortex. A particle prepa…
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…
