Polarization control of high-harmonic generation via the spin-orbit interaction
Jack Wragg, Daniel D. A. Clarke, Gregory S. J. Armstrong +3
We observe the generation of high harmonics in the plane perpendicular to the driving laser polarization and show that these are driven by the spin-orbit interaction. Using R-Matri…

Resolving Ultra-Fast Spin-Orbit Dynamics in Heavy Many-Electron Atoms
Jack Wragg, Daniel D. A. Clarke, Gregory S. J. Armstrong +3
We use R-Matrix with Time-dependence (RMT) theory, with spin-orbit effects included, to study krypton irradiated by two time-delayed XUV ultrashort pulses. The first pulse excites…

RMT: R-matrix with time-dependence. Solving the semi-relativistic, time-dependent Schrodinger equation for general, multi-electron atoms and molecules in intense, ultrashort, arbitrarily polarized laser pulses
Andrew Brown, Greg Armstrong, Jakub Benda +6
RMT is a program which solves the time-dependent Schrodinger equation for general, multielectron atoms, ions and molecules interacting with laser light. As such it can be used to m…
