3 scientists win Nobel Prize for work on electrons in atoms

STOCKHOLM

The Nobel Prize in physics was awarded Tuesday to three scientists who look at electrons in atoms during the tiniest of split seconds.

Pierre Agostini of The Ohio State University in the U.S.; Ferenc Krausz of the Max Planck Institute of Quantum Optics and Ludwig Maximilian University of Munich in Germany; and Anne L’Huillier of Lund University in Sweden won the award.

Their experiments “have given humanity new tools for exploring the world of electrons inside atoms and molecules,” according to the Royal Swedish Academy of Sciences, which announced the prize in Stockholm. They “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.”

At the moment, this science is about understanding our universe rather than practical applications, but the hope is that it will eventually lead to better electronics and disease diagnosis.

L’Huillier is only the fifth woman to win a Nobel in physics.

“This is the most prestigious and I am so happy to get this prize. It’s incredible," she told the news conference announcing the prize. "As you know there are not so many women who got this prize so it’s very special.”

The Nobel Prizes carry a cash award of 11 million Swedish kronor ($1 million). The money comes from a bequest left by the prize’s creator, Swedish inventor Alfred Nobel, who died in 1896.

Last year, three scientists jointly won the physics prize for proving that tiny particles could retain a connection with each other even when separated. The phenomenon was once doubted but is now being explored for potential real-world applications such as encrypting information.

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.

Nobel announcements will continue with the chemistry prize today and the literature prize tomorrow. The Nobel Peace Prize will be announced on Oct. 7 and the economics award on Oct. 9.
