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 …

Nonadiabatic transitions are one of the most important quantum mechanical phenomena in
chemical reaction dynamics. This is because the most interesting chemical and even …

We theoretically investigate the high-order harmonic generation in a helium atom with a two-
color optical field synthesized by an intense 6 fs pulse at 800 nm and a relatively weak 21.3 …

In this paper, we theoretically discuss the combined chirp effects on the isolated attosecond
generation when a model Ar is exposed to an intense 5-fs, 800-nm fundamental chirped …

Three alternative forms of harmonic spectra, based on the dipole moment, dipole velocity,
and dipole acceleration, are compared by a numerical solution of the Schrödinger equation …

We present a method of producing single attosecond pulses by using a few-cycle (5 fs)
driving pulse with two additional weak control pulses. We discuss how single attosecond …

Attoscience is the emerging field that accesses the fastest electronic processes occurring at
the atomic and molecular length scales with attosecond (1 as= 1 0− 18 s) time resolution …

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 …

We solve the time-dependent Schrödinger equation for atomic hydrogen in an intense field
using spherical coordinates with a radial grid and a spherical harmonic basis for the angular …

We present numerical simulations of high-order harmonic generation in helium using a
temporally synthesized and spatially nonhomogeneous strong laser field. The combination …
