Relativistic surfatron process for Landau resonant electrons in radiation belts [PDF]
Nonlinear Processes in Geophysics, 2014 Recent theoretical studies of the nonlinear wave-particle interactions for relativistic particles have shown that Landau resonant orbits could be efficiently accelerated along the mean background magnetic field for propagation angles θ in close proximity

Propagation of partially coherent radiation using Wigner functions
Physical Review Accelerators and Beams, 2021 Undulator radiation from synchrotron light sources must be transported down a beam line from the source to the sample. A partially coherent photon beam may be represented in phase space using a Wigner function, and its transport may use some similar ...
