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 …

We revisit the recollision picture of correlated multiphoton double ionization of atoms in
strong laser fields and develop consistent semiclassical model in the tunneling limit. We …

We present calculations of intense-field multiphoton ionization processes in helium at XUV
wavelengths. The calculations are obtained from a full-dimensional integration of the two …

We describe a new ab initio method for solving the time-dependent Schrödinger equation for
multi-electron atomic systems exposed to intense short-pulse laser light. We call the method …

We determine generalized cross sections for two-photon double ionization of He in the
photon energy region between 40.7 and 47 eV where absorption of two photons can lead to …

We present calculations of single-and double-ionization rates of helium at 390 nm, accurate
to within 10%, obtained from a full-dimensional integration of the time-dependent …

We report the implementation of a cost-effective approximation method within the framework
of the time-dependent optimized coupled-cluster (TD-OCC) method [T. Sato et al., J. Chem …

We analyze the role of multielectron dynamics in high-harmonic generation spectroscopy,
using an example of a two-electron system. We identify and systematically quantify the …

We report successful implementation of the time-dependent second-order many-body
perturbation theory using optimized orthonormal orbital functions called time-dependent …

We present calculations of the time delay between single and double ionization of helium,
obtained from full-dimensionality numerical integrations of the helium–laser Schrödinger …
