Energy level shift of quantum systems via the electric Aharonov-Bohm effect
RY Chiao, H Hart, NA Inan +4
A novel version of the electric Aharonov-Bohm effect is proposed where the quantum system which picks up the Aharonov-Bohm phase is confined to a Faraday cage with a time varying,…
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.…
Spin and spatial dynamics in electron-impact scattering off S-wave He using R-matrix with Time-Dependence theory
Jack Wragg, Hugo W. van der Hart
R-matrix with time-dependence theory is applied to electron-impact ionisation processes for He in the S-wave model. Cross sections for electron-impact excitation, ionisation and io…
Double Ionisation in R-Matrix Theory Using a 2-electron Outer Region
Jack Wragg, J. S. Parker, H. W. van der Hart
We have developed a two-electron outer region for use within R-matrix theory to describe double ionisation processes. The capability of this method is demonstrated for single-photo…
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(…
Time delay between photoemission from the 2p and 2s subshells of Neon
L. R. Moore, M. A. Lysaght, J. S. Parker +2
The R-Matrix incorporating Time (RMT) method is a new method for solving the time-dependent Schroedinger equation for multi-electron atomic systems exposed to intense short-pulse l…
