Table of Contents
In a world where the smallest particles defy our understanding, a groundbreaking innovation has emerged, sending ripples through the scientific community. researchers from UC San DiegoS Department of Chemistry and biochemistry have achieved the seemingly impossible: directly visualizing the motion of electrons within molecules.
Electrons, the tiny particles orbiting an atom’s nucleus, complete a cycle in mere hundredths of an attosecond—an unimaginably short timeframe. Their ultrafast movements have historically made direct observation a important challenge.however, this new technique, termed ultrafast vortex electron diffraction, allows for the direct visualization of electron movement at the attosecond scale.
The innovation lies in the use of a specialized, spiraling electron beam. This beam’s unique properties enable precise tracking of electron motion in both space and time. The method’s sensitivity to electronic coherence—the synchronized movement of electrons—is particularly noteworthy.By isolating these coherent electron dynamics from other processes, the technique opens doors to studying fundamental quantum processes, including investigating energy transfer and electron behavior in advanced materials.
The research, published February 19, 2025, in Physical Review Letters, was spearheaded by Haowei Wu and Haiwang Yong of UC San Diego. Their work was partially funded by the W. M. Keck foundation, leveraging computing resources at the W. M.Keck Laboratory for Integrated Biology at UC San Diego.
This technique’s unusual sensitivity to electronic coherences unlocks new possibilities for visualizing ultrafast quantum phenomena in molecules, bringing us closer to the ultimate goal of controlling chemical reactions at the most fundamental level.
