About :

The lecture by Dr. Nataša Vujičić as part of the "Nobel at the IRB" series was held on the occasion of the awarding of the Nobel Prize in Physics 2023. When we want to observe events that occur quickly, we get the appearance of continuous motion, like still images on film. If we want to investigate really short events, we need special technology. In the world of electrons, changes occur in a few dozen attoseconds - an attosecond is so short that there are as many of them in one second as there have been seconds since the birth of the universe. This year's Nobel Prize winners in Physics were recognized for their experiments that gave humanity new tools for exploring the world of electrons inside atoms and molecules. Pierre Agostini, Ferenc Krausz, and Anne L'Hullier demonstrated a way to create extremely short (attosecond) pulses of light that can be used to measure fast processes in which electrons move or change energy, enabling the investigation of processes that were so fast that they were previously impossible to track.
