The dynamics of electrons changes ever so slightly on each interaction with a photon. Physicists have now measured such interplay in its arguably purest form -- by recording the attosecond-scale time ...

Have you ever placed the palm of your left hand on the back of your right hand, in such a way that all fingers point in the same direction? If you have, then you probably know that your left thumb ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

If you were asked to picture how electrons move, you could be forgiven for imagining a stream of particles sluicing down a wire like water rushing through a pipe. After all, we often describe ...

Niranjan Shivaram receives funding from the National Science Foundation and U.S. Department of Energy. Electrons moving around in a molecule might not seem like the plot of an interesting movie. But a ...
