Sub-Cycle Optical Dynamics Captured by Attosecond Electron Microscopy.

Researchers have developed a new technique for attosecond electron microscopy that allows for the observation of sub-cycle optical dynamics in materials. The technique involves using tilted electron pulses to image electromagnetic waveforms with unprecedented temporal resolution. This could lead to new insights into the behavior of plasmonic and chiral nanostructures, as well as the study of ultrafast electron dynamics in materials.
