When light hits a material, the state of the electrons changes. So, what remains after the light has passed through?Counting ...

Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, ...

A new analysis reveals what happens when very short or narrow electron beams encounter a particle. The research is published in the New Journal of Physics. Scientists should be able to achieve a new ...

Two shaped laser pulses opened new electron excitation pathways and tracked rapid quantum dynamics in potassium atoms.

Kagome superconductor physics advances: physicists identify a chiral electron parent state in CsV3Sb5 that forms above 174 K and seeds chirality in both the charge density wave and superconducting ...
