Resonant inelastic X-ray scattering (RIXS) is a powerful technique that combines
spectroscopy and inelastic scattering to probe the electronic structure of materials. RIXS is …

Free-electron lasers and high-harmonic-generation table-top systems are new sources of
extreme-ultraviolet to hard X-ray photons, providing ultrashort pulses that are intense …

Revealing and clarifying the chemical reaction processes and mechanisms inside the
batteries will bring a great help to the controllable preparation and performance modulation …

We report the measurement of impulsive stimulated x-ray Raman scattering in neutral liquid
water. An attosecond pulse drives the excitations of an electronic wavepacket in water …

The free-electron laser in Hamburg, FLASH, is the first extreme ultra-violet and soft X-ray
free-electron laser (FEL) user facility and has been continuously upgraded since its start in …

All-optical switching (AOS) results in ultrafast and deterministic magnetization reversal upon
single laser pulse excitation, potentially supporting faster and more energy-efficient data …

Free-electron lasers provide bright, ultrashort, and monochromatic x-ray pulses, enabling
novel spectroscopic measurements not only with femtosecond temporal resolution: The high …

We describe an emerging hard X-ray spectroscopy technique, stimulated X-ray emission
spectroscopy (S-XES). S-XES has the potential to characterize the electronic structure of 3d …

There has been a rise of a new analysis method of nonlinear X-ray spectroscopy for
materials science. This book provides the basic principles for understanding the issue and …

In recent years, a series of noble metals and transition metal-based single-atom catalysts
(SACs) have been explored for electrochemical oxygen evolution reaction (OER). The …
