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 …

The theoretical description of the nonlinear photoionization of atoms and ions exposed to
high-intensity laser radiation is underlain by the Keldysh theory proposed in 1964. The …

Recent advances in laser technology have pushed the frontier of maximum intensity
achieved to about 1022W/cm2 and investigators currently believe even higher intensities …

Intense-field many-body S-matrix theory (IMST) provides a systematic ab initio approach to
investigate the dynamics of atoms and molecules interacting with intense laser radiation. We …

This paper reviews the knowledge of the structure, dynamics and collisions of atomic
negative ions, as accumulated at the end of 2003, and describes how the research exploring …

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 theory describing above-threshold ionization of atoms and ions in a strong
electromagnetic field is presented. It is based on the widely known strong field …

Nonperturbative analytical quantum treatments of strong-field laser-atom interaction are
essentially based on the assumption that binding forces are negligible once the electron is …

The adiabatic theory of ionization of an electron, initially bound in a three-dimensional
potential well, by an intense low-frequency laser pulse is developed. The general case of …

We present a model-independent theory for laser detachment of a weakly bound electron
having a nonzero angular momentum. Our treatment reduces to the well-known Keldysh …
