Scientific Highlights
The secret life of an electromagnon
SwissFEL sheds light on how lattice and atomic spins jiggle together.
Strong modulation of carrier effective mass in WTe2 via coherent lattice manipulation
Schematic ultrafast surface diffraction setup used for monitoring the crystal lattice in multiple directions.
Anomalous temperature dependence of the experimental x-ray structure factor of supercooled water
Supercooled water scattering signals show an anolmalous structure factor temperature dependence suggesting decreasing density at lowering temperatures below 236 K (-37°C).
Ultrafast electron localization
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.
Uniquely sharp X-ray view
A new PSI method allows quantum-physical research on materials with the aid of X-ray lasers.
Compact and high-performance, like a Swiss Army knife
The X-ray free-electron laser SwissFEL really is as high-performance and versatile as planned.
Conduction control in nanoparticles
Light induced propagation strain pulse, converting nanoparticles of Ti3O5 from semiconducting to metallic phase.
Ultrafast calorimetry of deeply supercooled water
FEL-based ultrafast calorimetry measurements show enhancement and maximum in the isobaric specific-heat.
Long-range coherent dynamics of bound electrons in a solid
Ultrafast long-range coherent dynamics in electronic structure excited by THz pulses and studied using free electron laser based resonant X-ray diffraction.
