Faster than a speeding bullet—the 2023 Physics Nobel Prize

Attosecond physics is a novel research field that pursues a better understanding of electron dynamics in atoms, molecules and condensed matter by means of pump-probe experiments where the motion of electrons are tracked with attosecond (1 as = 10 −18 s) time resolution. The 2023 Physics Nobel Prize was awarded to three experimental pioneers of the field, who developed the key methods to generate and characterize attosecond pulses.
