Attosecond science, honored with the 2023 Nobel Prize in Physics, is transforming our understanding of how electrons move in atoms, molecules, and solids. An attosecond—equivalent to a billionth ...

An attosecond is one quintillionth 10-18 of a second—a timescale that allows scientists to capture even the fastest electron movements ... group leader of the FEL physics group at the European ...

Attosecond physics is the study of atomic-scale electron dynamics in matter. Such dynamics are probed using attosecond light pulses: attosecond pulses present the same timescale of light-matter ...
