-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.…
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…
