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…
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…
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…
-matrix with Time-dependence Theory for Ultrafast Atomic Processes in Arbitrary Light Fields
D. D. A. Clarke, G. S. J. Armstrong, A. C. Brown +1
We describe an ab initio and non-perturbative -matrix with time-dependence theory for ultrafast atomic processes in light fields of arbitrary polarization. The theory is applica…
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.…
