Nobel Prize in Physics 2023: Pierre Agostini, Ferenc Krausz and Anne L’Huillier receive this year’s prize

This year’s Nobel Prize in Physics went to Pierre Agostini, Ferenc Krausz and Anne L’Huillier for their experiments with light that capture “the shortest moment”.

The Royal Swedish Academy of Sciences awarded the prize to the three physicists “for their experimental methods that generate attosecond pulses of light to study the dynamics of electrons in matter”.

Pierre Agostini is professor emeritus at Ohio State University, in the United States; Ferenc Krausz is director of the Max Planck Institute for Quantum Optics in Germany, and Anne L’Huillier is a professor at Lund University in Sweden.

The physicists’ work “demonstrated a way to create extremely short pulses of light that can be used to measure the rapid processes in which electrons move or change energy,” the Academy said.

The winners will share the cash prize of 10 million Swedish kronor ($966,000).

The Royal Swedish Academy of Sciences said the three laureates’ experiments produced “pulses of light so short that they are measured in attoseconds.”

An attosecond is one quintillionth of a second. “An attosecond is so short that the number of them in one second is equal to the number of seconds that have passed since the universe emerged, 13.8 billion years ago,” explains the Academy.

Physicists’ work has shown that these almost unimaginably short pulses could be used to capture images of processes occurring inside tiny atoms and molecules.

The Nobel Prize in Physiology or Medicine, announced this Monday, was awarded to professors Katalin Kariko and Drew Weissman, who developed the technology that gave rise to the mRNA vaccines against Covid.
