The angular momentum of molecules, or, equivalently, their rotation in three-dimensional
space, is ideally suited for quantum control. Molecular angular momentum is naturally …

The motion of electrons on the atomic scale has been hidden from direct experimental
access until recently. We review the revolution in technology that opened the door to real …

High-harmonic generation (HHG) is an extreme nonlinear process in which intense pulses
of light drive matter to emit high harmonics of the driving frequency, reaching the extreme …

The availability of attosecond-duration extreme ultraviolet or soft X-ray light sources has
opened up new fields of research in atomic and molecular physics. These pulses can be as …

We report attosecond-scale probing of the laser-induced dynamics in molecules. We apply
the method of high-harmonic spectroscopy, where laser-driven recolliding electrons on …

Nonadiabatic dynamics around an avoided crossing or a conical intersection play a crucial
role in the photoinduced processes of most polyatomic molecules. The present work shows …

Sources of short wavelength radiation with femtosecond to attosecond pulse durations, such
as synchrotrons or free electron lasers, have already made possible numerous, and will …

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 …

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 …

Time-delays in the photoionization of molecules are investigated. As compared to atomic
ionization, the time-delays expected from molecular ionization present a much richer …
