The exploration of the unique properties of stored and cooled beams of highly-charged ions
as provided by heavy-ion storage rings has opened novel and fascinating research …

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 …

The advent of free electron laser (FEL) facilities capable of delivering high intensity pulses in
the extreme-UV to X-ray spectral range has opened up a wide vista of opportunities to study …

In parallel with the evolution of femtosecond and attosecond laser as well as free-electron
laser technology, a variety of theoretical methods have been developed to describe the …

The pulse duration of soft x-ray free-electron laser (FEL) radiation is directly measured by
time-resolved observation of doubly charged helium ions at 51.8 eV. A wave front splitting …

Recent experimental developments of high-intensity, short-pulse extreme ultraviolet light
sources are enhancing our ability to study electron-electron correlations. We perform time …

We present kinematically complete data on two-photon double ionization of Ne induced by
short (∼ 25 fs) intense (∼ 5× 10 13 W cm− 2) free-electron laser pulses at 44 eV. The …

We present cross sections for electron-impact ionization and simultaneous ionization plus
excitation of helium by electron impact. The results are obtained from a fully nonperturbative …

Multifunctional materials have attracted tremendous attention in intelligent and interactive
devices. However, achieving multi-dimensional sensing capabilities with the same …

Double ionization of helium by a single intense (above 10 18 W/cm 2) linearly polarized
extreme ultraviolet laser pulse is studied by numerically solving the full-dimensional time …
