Scientists get dramatically better resolution at X-ray free-electron lasers with a new technique.

Just as pressing a guitar string produces a higher pitch, sending laser light through a material can shift it to higher energies and higher frequencies. Now scientists have discovered how to use this phenomenon to explore quantum materials in a...

These fleeting disruptions, seen for the first time in lead hybrid perovskites, may help explain why these materials are exceptionally good at turning sunlight into electrical current in solar cells.

The results, which show that ultrafast atomic motions are the first step in forming a magnetic state, could lead to faster and more efficient data storage devices.

A better understanding of how this happens could help researchers hone future electronic measurements and offer insights into how X-rays interact with matter on ultrafast time scales.

The initiative will give scientists more access to powerful lasers at universities and labs.

FACET-II will pave the way for a future generation of particle colliders and powerful light sources, opening avenues in high-energy physics, medicine, and materials, biological and energy science.

This leap in capability will allow scientists to investigate quantum and chemical systems more directly than ever before.

The technique could improve the efficiency of data collection and pave the way for new kinds of experiments.
