X-ray spectroscopy is an important tool for scientific analysis. While the earliest
demonstration experiments were realised in the laboratory, with the advent of synchrotron …

We review the tremendous advances in ultrafast X-ray science, over the past 15 years,
making the best use of new ultrashort X-ray sources including table-top or large-scale …

Ferromagnetic or antiferromagnetic spin ordering is governed by the exchange interaction,
the strongest force in magnetism,,,. Understanding spin dynamics in magnetic materials is …

Irradiating a ferromagnet with a femtosecond laser pulse is known to induce an ultrafast
demagnetization within a few hundred femtoseconds. Here we demonstrate that direct laser …

For an isolated quantum particle, such as an electron, the orbital (L) and spin (S) magnetic
moments can change provided that the total angular momentum of the particle is conserved …

Synchrotrons and free-electron lasers are the most powerful sources of X-ray radiation. They
constitute invaluable tools for a broad range of research; however, their dependence on …

Over more than a century, X-rays have transformed our understanding of the fundamental
structure of matter and have been an indispensable tool for chemistry, physics, biology …

Sooner or later, fundamental limitations destine complementary metal-oxide-semiconductor
(CMOS) scaling to a conclusion. A number of unique switches have been proposed as …

Conspectus The properties of transition metal complexes are interesting not only for their
potential applications in solar energy conversion, OLEDs, molecular electronics, biology …

Capturing the evolving geometric and electronic structure in the course of a chemical
reaction or biological process is the principal aim of time-resolved X-ray spectroscopies …
