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…
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…
Direct versus Delayed pathways in Strong-Field Non-Sequential Double Ionization
A. Emmanouilidou, J. S. Parker, L. R. Moore +1
We report full-dimensionality quantum and classical calculations for double ionization of laser-driven helium at 390 nm. Good qualitative agreement is observed. We show that the cl…
A combined R-matrix eigenstate basis set and finite-differences propagation method for the time-dependent Schr\"{od}dinger equation: the one-electron case
L. A. A. Nikolopoulos, J. S. Parker, K. T. Taylor
In this work we present the theoretical framework for the solution of the time-dependent Schrödinger equation (TDSE) of atomic and molecular systems under strong electromagnetic fi…
