A new research study from Opto-Electronic Advances discusses tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography. In recent years, the ...

In most materials, however, electron interactions are very weak and, therefore, hard to detect. One of the tricks that researchers have used for a while now consists in reducing the motional energy of ...

This new method describes an experimental concept called ultrafast vortex electron diffraction, which allows for direct visualization of electron movement in molecules on attosecond timescales.

while the surrounding spins gradually twist and point downwards to create a magnetic vortex. As an electron moves through a ...
