Less than a millionth of a billionth of a second long, attosecond X-ray pulses allow researchers to peer deep inside molecules and follow electrons as they zip around and ultimately initiate chemical reactions.
Researchers demonstrate a new ability to drive and track electronic motion, which is crucial to understanding the role of electrons in chemical processes and how quantum coherence evolves on the shortest timescales.
A major international effort at SLAC is focused on improving our views of intact viruses, living bacteria and other tiny samples using the brightest X-ray light on Earth.
In this lecture, SLAC’s Ryan Coffee explains how researchers are beginning to use pattern recognition and machine learning to study chemical reactions at the level of atoms and molecules with the LCLS X-ray laser.
An experiment revealed a well-organized 3-D grid of quantum "tornadoes" inside microscopic droplets of supercooled liquid helium – the first time this formation has been seen at such a tiny scale.
