Multiphoton Processes in a Two-Electron Atom Using a Cray T3D
Many-electron atoms interacting with intense coherent radiation presents many new challenges for the theorist. Theory was stimulated enormously in recent years by the discovery of high harmonic generation in c...

Numerical Grid Methods
Over recent years in Belfast we have developed numerical grid methods for solving the two-electron time-dependent Schrödinger equation (TDSE) in its full-dimensionality 1–4]. We have specifically had in mind d...

Laser-driven helium at 780 nm
We briefly review the methods under development at Queen’s University Belfast to solve the full-dimensionality time-dependent Schrödinger equation for helium in intense laser fields. We set out the computation...

Dissociative ionization of molecules in intense laser fields
Accurate and efficient grid based techniques for the solution of the time-dependent Schrödinger equation for few-electron diatomic molecules irradiated by intense, ultrashort laser pulses are described. These ...

Modelling non-adiabatic processes using correlated electron-ion dynamics
Here we survey the theory and applications of a family of methods (correlated electron-ion dynamics, or CEID) that can be applied to a diverse range of problems involving the non-adiabatic exchange of energy ...

On the stability of hole states in molecules and clusters
Recent investigations of the electron dynamics of molecules after irradiation with a short, strong XUV pulse have shown that under certain conditions, a rather clean deep hole state can be generated which, in ...

Open AccessDipole instability in molecules irradiated by XUV pulses
We study the response of small covalent molecules to XUV laser pulses. The theoretical description relies on a real-time and real-space Time-Dependent Density Functional Theory (TDDFT) approach at the level of...
