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…
Electron correlation and short-range dynamics in attosecond angular streaking
G. S. J. Armstrong, D. D. A. Clarke, J. Benda +2
We employ the R-matrix with time-dependence method to study attosecond angular streaking of F. Using this negative ion, free of long-range Coulomb interactions, we elucidate th…
Modeling tomographic measurements of photoelectron vortices in counter-rotating circularly polarized laser pulses
G. S. J. Armstrong, D. D. A. Clarke, J. Benda +3
Recent experiments [D. Pengel, S. Kerbstadt, L. Englert, T. Bayer, and M. Wollenhaupt, \href{https://journals.aps.org/pra/abstract/10.1103/PhysRevA.96.043426}{{\PRA} {\bf 96} 04342…
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…
Electron rotational asymmetry in strong-field photodetachment from F by circularly polarized laser pulses
G. S. J. Armstrong, D. D. A. Clarke, A. C. Brown +1
We use the -matrix with time-dependence method to study detachment from F in circularly-polarized laser fields of infrared wavelength. By decomposing the photoelectron momen…
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…
