Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

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 …

Describing harmonic generation (HG) in terms of a system's complex quasienergy, the
harmonic power P Δ E (λ)(over a fixed interval, Δ E, of harmonic energies) is shown to …

A closed-form analytic formula for high-order harmonic generation (HHG) rates for atoms
(that generalizes an HHG formula for negative ions [MV Frolov, J. Phys. B 42, 035601 (2009) …

The quantum-mechanical transition amplitudes for atomic and molecular processes in
strong laser fields are expressed in the form of multidimensional integrals of highly …

Analytic formulae describing harmonic generation by a weakly bound electron are derived
quantum mechanically in the tunnelling limit. The formulae confirm the classical three-step …

The quantum-mechanical transition amplitude of an ionization process induced by a strong
laser field is typically expressed in the form of an integral over the ionization time of a highly …

The wave function of an electron interacting with a finite-range potential and an intense low-
frequency laser pulse is analyzed within the adiabatic approximation. The closed analytic …

We present a theoretical model for describing the interaction of an electron, weakly bound in
a short-range potential, with an intense, few-cycle laser pulse. General definitions for the …

We show that the quasistatic dipole moment can be induced by a short extreme ultraviolet
(XUV) pulse (XUV rectification effect) in atomic gas medium subjected to an intense infrared …
