An Overview of Relativistic Particle Pushers and their Extension to Arbitrary Order Accuracy
Holger Schmitz
Particle in Cell (PIC) simulations have become a vital tool for the investigation of kinetic processes in plasma physics. Many of the systems investigated with PIC simulations cont…
A beat wave approach to harmonic generation in chiral media
Raoul Trines, Holger Schmitz, Robert Bingham +4
We extend the beat-wave framework for laser harmonic generation - where spectra form regular lattices in Fourier space - to the nonlinear response of isotropic chiral media driven…
Dynamical symmetries in laser harmonic generation via a cubic nonlinearity
Raoul Trines, Holger Schmitz, Martin King +2
In our earlier work on harmonic generation with complex light [Nature Communications 15, 6878 (2024)], we demonstrated how the harmonic spectrum of a complex laser beam in a nonlin…
A tuneable frequency comb via dual-beam laser-solid harmonic generation
Raoul Trines, Holger Schmitz, Martin King +2
A high-power laser pulse at normal incidence onto a plane solid target will generate odd harmonics of its frequency. However, the spacing of the harmonic lines in this configuratio…
