This advance in attosecond science, the study of the fastest phenomena in nature, could have a wide variety of future applications, paving the way for ultrafast communications and computing.

We then use the simultaneous collection of attosecond transient absorption spectroscopy (ATAS) and ATGS to determine ultrafast changes in the refractive index, with which a phonon diffusion process ...
