Strong laser pulses enable probing molecules with their own electrons. The oscillating electric field tears electrons off a molecule, accelerates them, and drives them back toward their parent ion within a few femtoseconds. The electrons are then dif

Publikováno v: The International Conference on Ultrafast Phenomena (UP) 2022.

A novel light source delivering few-cycle UV pulses is used to reveal an ultrafast modulation of the chiroptical properties of photoexcited chiral molecules, probed by time-resolved photoelectron circular dichroism. We report a periodic inversion of
