Femtosecond insights into laser-assisted photoemission from metal surfaces
The recent advancements in high-intensity ultrafast X-ray science have paved the way for a new era of time-resolved pump-probe experiments: They have the potential to reveal previously inaccessible information about the interactions of photons with surfaces and the electronic dynamics they induce. This study presents an innovative investigation of the laser-assisted photoelectric effect (LAPE) from metallic ...28 January 2025
A Global Vision for Helical X-Ray-Laser Pulses to Unveil Life’s Fastest Movements
Over the past years, scientists worldwide have collaborated extensively to develop cutting-edge approaches with helical free-electron laser (FEL) pulses. These advancements aim to capture some of the fastest motions in nature, exploring them at the level of specific elements with a special ‘twist’. In Physical Review Research, leading experts from institutions such as the University of Hamburg, DESY, European ...
