Pierre Agostini, Ferenc Krausz and Anne L’Huillier share the 2023 Nobel Prize in Physics for experiments that “have given humanity new tools for exploring the world of electrons inside atoms and molecules.” A more succinct description is that they have given us attosecond physics.
Attosecond physics is the science of the exceedingly, extremely, exceptionally [insert your own hyperbolic adverb here] fast. To put it into context, L’Huillier’s first call from the Nobel Prize’s Adam Smith after she received the news took 3 minutes 48 seconds, or-1 attoseconds. Her first heartbeat during that call lasted a second, or a billion billion attoseconds. Almost defying a description, an attosecond is an unfathomably tiny amount of time. But it happens to be the natural timescale of the near-instantaneous dance of electrons.
