Advances in attosecond science have led to a wealth of important discoveries in atomic,
molecular, and solid-state physics and are progressively directing their footsteps toward …

The past decade has witnessed an increasing interaction between experiment and theory in
the field of molecular spectroscopy. On the computational side, ongoing developments of …

Recent years have witnessed an increasing interest in time‐dependent coupled‐cluster
(TDCC) theory for simulating laser‐driven electronic dynamics in atoms and molecules, and …

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 …

UKRmol+ is a new implementation of the time-independent UK R-matrix electron–molecule
scattering code. Key features of the implementation are the use of quantum chemistry codes …

A new approach to finite basis sets for the Dirac equation is developed. It does not involve
spurious states and improves the convergence properties of basis-set calculations …

Time delays of electrons emitted from an isotropic initial state with the absorption of a single
photon and leaving behind an isotropic ion are angle independent. Using an interferometric …

BSR is a general program to calculate atomic continuum processes using the B-spline R-
matrix method, including electron–atom and electron–ion scattering, and radiative …

Electron-impact ionization of the hydrogen atom is the prototypical three-body Coulomb
breakup problem in quantum mechanics. The combination of subtle correlation effects and …

The Qprop package is presented. Qprop has been developed to study laser–atom
interaction in the nonperturbative regime where nonlinear phenomena such as above …
