The history and current status of the Keldysh theory of strong field ionization are reviewed.
The focus is on the fundamentals of the theory, its most important applications and those …

Photoelectron holography constitutes a powerful tool for the ultrafast imaging of matter, as it
combines high electron currents with subfemtosecond resolution, and gives information …

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 …

A review is presented of the rescattering plateau in laser-induced above-threshold ionization
and its various features as they were discovered over time. Several theoretical explanations …

Using the recently developed Coulomb quantum orbit strong-field approximation, we
perform a systematic analysis of several features encountered in above-threshold ionization …

We show that the electrons, produced in strong-bicircular-field-induced above-threshold
ionization of inert-gas atoms, have a large spin asymmetry if the ions exhibit fine-structure …

The velocity map of the above-threshold ionization electron spectrum at long laser
wavelength exhibits a characteristic structure normal to the laser polarization, which has the …

The low-energy structure (LES) in the energy spectrum of above-threshold ionization of rare-
gas atoms is reinvestigated from three different points of view. First, the role of forward …

Above-threshold ionization of rare-gas atoms by a bicircular field with its two components
counterrotating is theoretically investigated by means of the improved strong-field …

Multipath holographic interference in strong-field quantum tunnel ionization is key to
revealing subangstrom attosecond dynamics for molecular movies. This critical subcycle …
