Attosecond science, born at the beginning of this century with the generation of the first
bursts of light with durations shorter than a femtosecond, has opened the way to look at …

Three decades ago, a highly nonlinear nonpertubative phenomenon, now well-known as
the high harmonic generation (HHG), was discovered when intense laser irradiates gaseous …

Molecules constituted by different isotopes are different in vibrational modes, making it
possible to elucidate the mechanism of a chemical reaction via the kinetic isotope effect …

The formulation of the parabolic adiabatic expansion approach to the problem of ionization
of atomic systems in a static electric field, originally developed for the axially symmetric case …

Molecular high-order harmonic generation (MHOHG) in a non-Born-Oppenheimer treatment
of H 2+, D 2+, is investigated by numerical simulations of the corresponding time-dependent …

Time-resolved photoelectron holography from atoms using midinfrared laser pulses is
investigated by solving the corresponding time-dependent Schrödinger equation (TDSE) …

We investigate the high-order-harmonic generation (HHG) from solids by simulating the
dynamics of a single active electron in periodic potentials. The corresponding time …

High harmonic generation (HHG) in crystals has revealed a wealth of perspectives such as
all-optical mapping of the electronic band structure, ultrafast quantum information, and the …

The molecular high-order-harmonic generation (molecular HHG) of HeH 2+ is investigated
by numerical integration of the non-Born-Oppenheimer time-dependent Schrödinger …

Motivated by the ongoing controversy over the origin of the nonlinear index saturation and
subsequent intensity clamping in femtosecond filaments, we study the atomic nonlinear …
