Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

New free-electron laser and high-harmonic generation X-ray light sources are capable of
supplying pulses short and intense enough to perform resonant nonlinear time-resolved …

The characteristic excitation of a metal is its plasmon, which is a quantized collective
oscillation of its electron density. In 1956, David Pines predicted that a distinct type of …

In order to improve the advantages and the reliability of the second derivative method in
tracking the position of extrema from experimental curves, we develop a novel analysis …

The macroscopic characteristics of a material are determined by its elementary excitations,
which dictate the response of the system to external stimuli. The spectrum of excitations is …

A compilation of procedures for planning and performing X-ray Raman scattering (XRS)
experiments and analyzing data obtained from them is presented. In particular, it is …

Water is ubiquitous on earth, but we know little about the real-space motion of molecules in
liquid water. We demonstrate that high-resolution inelastic x-ray scattering measurement …

Time-domain techniques have shown the potential of photomanipulating existing orders and
inducing new states of matter in strongly correlated materials. Using time-resolved exact …

Single-shot ultrafast imaging reveals the transient dynamics of ultrafast phenomena. Herein,
we introduce a new approach for capturing ultrafast micron-scale dynamics using an …

The screening arising from many-body excitations is a crucial quantity for describing
absorption and inelastic X-ray scattering (IXS) of materials. Similarly, the electron screening …
