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…
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…
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…
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…
On the Cooper Minimum in Singly ionized and Neutral Argon
O. Hassouneh, N. B. Tyndall, J. Wragg +2
We present an analysis of the appearance of the Cooper Minimum in singly ionized argon in both the photoionization cross-section (PICS) and high-harmonic generation (HHG) spectrum.…
