Ultrafast vortex electron diffraction: A new way to observe electrons in motion

Electrons oscillate around the nucleus of an atom on extremely short timescales, typically completing a cycle in just a few ...

An atom shuffles its electrons at ultrahigh speed — and is caught in the act

Pairs of light waves can be used to observe and manipulate a single electron as it moves inside an atom — motion that happens on the timescale of one-millionth of one-billionth of a second. Physicists ...
