The 2023 Nobel Prize for Physics has been awarded to to Pierre Agostini, Ferenc Krausz, Anne L’Huillier for research onelectrons in flashes of light
The 2023 Nobel Prize in Physics has been awarded to Pierre Agostini, Ferenc Krausz, and Anne L’Huillier “for experimental methods that generate attosecond pulses of light for the study of electro dynamics in matter”, The Royal Swedish Academy of Science announced on October 3, 2023.
The three Nobel Laureates in Physics 2023 are being recognised for their experiments, which have given humanity new tools for exploring the world of electrons inside atoms and molecules. Pierre Agostini, Ferenc Krausz and Anne L’Huillier have 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 press release said.
Their experiments granted the Laureates to observe extremely brief events that transpire in a few tenths of attoseconds—a quintillionth (10−18) of a second. An attosecond is so short that there are as many in one second as there have been seconds since the birth of the universe.
This brief pulses of light can be used to provide images of what occurs inside atoms and molecules.
The research conducted by the Laureates over a span of several decades allowed them to investigate processes that were so rapid that they were previously impossible to follow. This new technology is important to understand and control how electrons behave in a material.
Last year, The Nobel Prize in Physics was awarded to Alain Aspect, John F. Clauser and Anton Zeilinger for their work on quantum mechanics, the academy announced the winners on October 4, 2022. The award was given for experiments with entangled photons, establishing the violation of Bell inequalities, and pioneering quantum information science..
The physics prize comes a day after Hungarian-American Katalin Karikó and American Drew Weissman won the Nobel Prize in medicine for discoveries that enabled the creation of mRNA vaccines against COVID-19.

“I’ve never even been to these places before,” she laughed, “and suddenly I have memories in all of them.” The dates, she added, were genuinely good — long walks, easy conversations, and meals that stretched late into the evening — and the best part was that none of it felt heavy. The boys she met are all planning to visit her in Mumbai soon, not under without any pressure but with a sense of pleasant continuity. “I’m great,” she said, and she meant it.
