A recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

The R-matrix method is an embedding procedure which is based on the division of space
into an inner region where the physics is complicated and an outer region for which greatly …

Abstract We describe the Breit–Pauli distorted wave (BPDW) approach for the electron-
impact excitation of atomic ions that we have implemented within the autostructure code …

The dissociation of a wide range of oxygen-containing molecules following impact with
electrons of carefully controlled energy is critically reviewed. Molecules considered range …

Attosecond photoionization time delays reveal information about the potential energy
landscape that an outgoing electron wavepacket probes upon ionization. In this study, we …

We present accurate time-dependent ab initio calculations on fully differential and total
integrated (generalized) cross sections for the nonsequential two-photon double ionization …

In this review, we will focus on the theoretical aspects in observing and controlling the
electronic dynamics in few-electron atoms and molecules by attosecond pulses in different …

The past decade has seen extraordinary theoretical progress in the field of fully
kinematically resolved atomic electron-impact ionisation, and its closely related field of …

We present fully ab initio simulations of attosecond streaking for ionization of helium
accompanied by shakeup of the second electron. This process represents a prototypical …

In parallel with the evolution of femtosecond and attosecond laser as well as free-electron
laser technology, a variety of theoretical methods have been developed to describe the …
