Directly observing atomic motions in molecules during chemical dynamics has long
constituted one of the grand challenges in chemistry. 1 The emergence of X-ray free …

Fluctuations and stochastic transitions are ubiquitous in nanometre-scale systems,
especially in the presence of disorder. However, their direct observation has so far been …

Abstract X-ray Free Electron Lasers provide femtosecond x-ray pulses with narrow
bandwidth and unprecedented peak brightness. Special modes of operation have been …

With the introduction of x-ray free electron laser sources around the world, new scientific
approaches for visualizing matter at fundamental length and time-scales have become …

Considering the growing interest in magnetic materials for unconventional computing, data
storage, and sensor applications, there is active research not only on material synthesis but …

Van der Waals (vdW) magnetic materials are comprised of layers of atomically thin sheets,
making them ideal platforms for studying magnetism at the two-dimensional (2D) limit. These …

Advanced experimental measurements are crucial for driving theoretical developments and
unveiling novel phenomena in condensed matter and materials physics, which often suffer …

We investigate the microwave spin excitations of the cubic chiral magnet Fe 0.75 Co 0.25 Si
as driven by the thermal modulation of magnetic interactions via laser heating and probed …

The PERCIVAL detector is a CMOS imager designed for the soft X-ray regime at photon
sources. Although still in its final development phase, it has recently seen its first user …

Many magnetic equilibrium states and phase transitions are characterized by fluctuations.
Such magnetic fluctuation can, in principle, be detected with scattering-based x-ray photon …
