Two-dimensional simulation of the spin flip in the Kapitza-Dirac effect

P Ge, S Ahrens, B Shen - Physical Review A, 2024 - APS
Many calculations in strong-field quantum field theory are carried out by using a simple field
geometry, often neglecting the spatial field envelope. In this paper, we simulate the electron …
