Enhancing spin polarization using ultrafast angular streaking
Gregory S. J. Armstrong, Daniel D. A. Clarke, Jakub Benda +3
Through solution of the multielectron, semi-relativistic, time-dependent Schrödinger equation, we show that angular streaking produces strongly spin-polarized electrons in a noble…
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…
Extreme-ultraviolet-initiated High-harmonic Generation in Ar
D. D. A. Clarke, H. W. van der Hart, A. C. Brown
We employ the R-matrix with time-dependence method to investigate extreme-ultraviolet-initiated high-harmonic generation (XIHHG) in Ar. Using a combination of extreme-ultravi…
Electron rescattering in strong-field photodetachment of F
O. Hassouneh, S. Law, S. F. C. Shearer +2
We present ab initio studies of photoelectron spectra for above threshold detachment (ATD) of F anions in short, 1300 nm and 1800 nm laser pulses. We identify and assess the im…
