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…

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…
