When an atom or molecule is exposed to a short intense laser pulse, electrons that were
removed at an earlier time may be driven back by the oscillating electric field of the laser to …

We present an implementation of the time-dependent configuration-interaction singles
(TDCIS) method for treating atomic strong-field processes. In order to absorb the …

A comprehensive quantitative rescattering (QRS) theory for describing the production of high-
energy photoelectrons generated by intense laser pulses is presented. According to the …

Dynamic imaging of the molecular structure of H 2+ is investigated by attosecond
photoelectron holography. The interference between direct (reference) and backward …

Atomic and molecular ions generated by a strong optical laser pulse are not in general in the
electronic ground state. The density matrix for such ions is characterized by the electronic …

We use differential holography to overcome the forward scattering problem in strong-field
photoelectron holography. Our differential holograms of H 2 and D 2 molecules exhibit a …

We present a time-dependent density-functional method able to describe the photoelectron
spectrum of atoms and molecules when excited by laser pulses. This computationally …

Time-resolved molecular imaging is a frontier of ultrafast optical science and physical
chemistry. In this article, we review present and future key spectroscopic and microscopic …

We study the phase structure of the tunneling wave packets from strong-field ionization of
molecules and present a molecular quantum-trajectory Monte Carlo model to describe the …

We present a summarizing account of a series of investigations of high-order harmonic
generation (HHG) in diatomic molecules beyond the single-active electron and single-active …
