Compact Petawatt-Class Laser Wakefield Acceleration with Plasma Telescope
Xuesong Geng, Liangliang Ji, Baifei Shen
The compactness of laser wakefield acceleration (LWFA) is limited by its long focal length for high power lasers, e.g., more than 10 meters for 1-peatawatt (PW) laser pulse and up…
Extremely powerful and frequency-tunable terahertz pulses from a table-top laser-plasma wiggler
Jie Cai, Yinren Shou, Yixing Geng +6
The production of broadband, terawatt terahertz (THz) pulses has been demonstrated by irradiating relativistic lasers on solid targets. However, the generation of extremely powerfu…
Preliminary Exploration of Areal Density of Angular Momentum for Spiral Galaxies
Lan Zhang, Feilu Wang, Xiangxiang Xue +4
The specific angular momenta () of stars, baryons as a whole and dark matter haloes contain clues of vital importance about how galaxies form and evolve. Using a sample of 70…
Two-dimensional simulation of the spin-flip in the Kapitza-Dirac effect
Ping Ge, Sven Ahrens, Baifei Shen
Many calculations in strong field quantum field theory are carried out by using a simple field geometry, often neglecting the spacial field envelope. In this article, we simulate t…
Perturbative solution approach for computing the two-photon Kapitza-Dirac effect in a Gaussian beam standing light wave
Sven Ahrens, Chong Zhang, Ping Ge +2
Theoretical spin properties of the Kapitza-Dirac effect beyond the plane-wave description are not known in detail. We develop a method for computing electron diffraction of the two…
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…
