The goal of the present article is to review the major developments that have led to the
current understanding of molecule–field interactions and experimental methods for …

We demonstrate theoretically that the temporal structure of high harmonic x-ray pulses
generated with midinfrared lasers differs substantially from those generated with near …

Time-resolved investigations of ultrafast electronic and molecular dynamics were not
possible until recently. The typical time scale of these processes is in the picosecond to …

Investigation on structures in the high-harmonic spectrum has provided profuse information
of molecular structure and dynamics in intense laser fields, based on which techniques of …

Absorbing boundaries are frequently employed in real-time propagation of the Schrödinger
equation to remove spurious reflections and efficiently emulate outgoing boundary …

We align nonadiabatically an ensemble of N 2 in air, and irradiate the ensemble with linearly
polarized intense few-cycle laser pulses to generate population-inverted N 2+ ions. By …

Photoionization of molecular species is, essentially, a multipath interferometer with both
experimentally controllable and intrinsic molecular characteristics. In this work, XUV …

We experimentally and theoretically analyze the manifestations of quantum interference and
multiple ionization channels (multiple orbitals) in high-harmonic spectra of aligned N 2 O …

We exploit the relationship between high harmonic generation (HHG) and the molecular
photorecombination dipole to extract the molecular-frame differential photoionization cross …

We present molecular-frame high-harmonic spectroscopic measurements of the spectral
intensity and group delay of carbon dioxide. Using four different driving wavelengths and a …
