The study of onset and decay, as well as control of ultrafast quantum coherence in many-
electron systems is in the focus of interest of attosecond physics. Interpretation of attosecond …

The perceived dichotomy between analytical and ab initio approaches to theory in
attosecond science is often seen as a source of tension and misconceptions. This Topical …

We employ the recently developed multiphoton R-matrix method for molecular above-
threshold photoionization to obtain second-order ionization amplitudes that govern the …

We investigate the role of nuclear motion and strong-field-induced electronic couplings
during the double ionization of deuterated water using momentum-resolved coincidence …

We have evaluated total and partial photoionization cross sections, β asymmetry
parameters, and molecular frame photoelectron angular distributions (MFPADs) of the water …

Using a strong-field-approximation theory, we investigate the high-order above-threshold
ionization of diatomic molecules exposed to the monochromatic and bichromatic elliptically …

The dramatic progress of experimental attosecond science has called for the development of
new theoretical and computational tools capable of accurately model the correlated electron …

A multicenter (LCAO) B-spline basis is described in detail, and its capabilities concerning
affording convergent solutions for electronic continuum states and wavepacket propagation …

We address extreme-ultraviolet (XUV) initiated high-order harmonic generation (XIHHG) in
argon atoms observing a resonant enhancement of the high-energy harmonics when the …

We present a grid-based implementation of the time-dependent configuration-interaction
singles method suitable for computing the strong-field ionization of small gas-phase …
