The accurate measurement of time lies at the heart of experimental science, and is relevant
to everyday life. Extending chronoscopy to ever shorter timescales has been the key to …

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 …

We study the generation of high-harmonic radiation by Bloch electrons in a model
transparent solid driven by a strong midinfrared laser field. We solve the single-electron time …

For the past several decades, we have been able to directly probe the motion of atoms that
is associated with chemical transformations and which occurs on the femtosecond (10− 15 …

Entanglement is one of the most intriguing aspects of quantum mechanics and lies at the
heart of the ongoing second quantum revolution, where it is a resource that is used in …

Calculations are presented of vibrational wave packet dynamics in H 2+ ions formed by
ionization of neutral H 2 by a pair of attosecond extreme ultraviolet laser pulses, using time …

High harmonic light sources make it possible to access attosecond timescales, thus opening
up the prospect of manipulating electronic wave packets for steering molecular dynamics …

We report experiments where hydrogen molecules were dissociatively ionized by an
attosecond pulse train in the presence of a near-infrared field. Fragment ion yields from …

This review article focuses on imaging and controlling ultrafast dynamics of the hydrogen
molecule and its cation, initiated by ultrashort laser pulses. We discuss the mechanisms …

Since the first isolated attosecond pulse was demonstrated through high-order harmonics
generation (HHG) in 2001, researchers' interest in the ultrashort time region has expanded …
