Attosecond X-ray sources, methods, and applications at present and future free-electron lasers: tutorial

Le résumé fourni par la source

The timescale for electrons to break interatomic bonds during photoinduced physical or biochemical processes such as vision or photosynthesis is femtoseconds or less. For this reason, electron dynamics in a chemical bond must be viewed with attosecond pulses, but until now, laboratory attosecond sources have been too slow or weak to capture this intrabond motion. Tunable, powerful, attosecond X-rays from free-electron lasers now fill this gap and enable the first studies of site-specific electron motion within molecules, to the best of our knowledge. Here we explain how these sources work and how to use them to explore the attosecond frontier of physics, chemistry, and biology.
