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 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.…
The influence of multiple ionization thresholds on harmonic generation: Ar+
A. C. Brown, H. W. van der Hart
We apply time-dependent R-matrix theory to investigate harmonic generation from ground state Ar+ with M=0 at a wavelength of 390 nm. Contributions associated with the different 3s(…
