SwissFEL sheds light on how lattice and atomic spins jiggle together.
Schematic ultrafast surface diffraction setup used for monitoring the crystal lattice in multiple directions.
Supercooled water scattering signals show an anolmalous structure factor temperature dependence suggesting decreasing density at lowering temperatures below 236 K (-37°C).
This experiment performed at SwissFEL shows how fast we can localize electrons out of an electron gas into correlated, well localized states of a material. It is based on a combined ultrafast x-ray absorption and diffraction experiment on an intermetallic system.
A new PSI method allows quantum-physical research on materials with the aid of X-ray lasers.
The X-ray free-electron laser SwissFEL really is as high-performance and versatile as planned.
Light induced propagation strain pulse, converting nanoparticles of Ti3O5 from semiconducting to metallic phase.
FEL-based ultrafast calorimetry measurements show enhancement and maximum in the isobaric specific-heat.
Ultrafast long-range coherent dynamics in electronic structure excited by THz pulses and studied using free electron laser based resonant X-ray diffraction.
