Nobel Prize in Physics Awarded to 3 Scientists for Work on Electrons Nobel Prize in Physics Awarded to 3 Scientists for Work on Electrons
(32 minutes later)
The Nobel Prize in Physics was awarded to three scientists — Pierre Agostini, Ferenc Krausz and Anne L’Huillier — on Tuesday for their experiments that have “have given humanity new tools for exploring the world of electrons inside atoms and molecules.” The Nobel Prize in Physics was awarded to Pierre Agostini, Ferenc Krausz and Anne L’Huillier on Tuesday for their experiments that “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 awarding committee said.
Their work, the committee said, concerns “experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter.”Their work, the committee said, concerns “experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter.”
Eva Olsson, the chair of the Nobel Committee for Physics, said at a news conference on Tuesday that attosecond science “allows us to address fundamental questions” such as the time scale of the photoelectric effect for which Albert Einstein received the 1921 Nobel in Physics.
An attosecond is a millionth of a trillionth of a second. The number of them in one second is the same as the number of seconds that have elapsed since the universe came into existence, 13.8 billion years ago, according the Royal Swedish Academy of Sciences, which awards the physics prize.
The three laureates’ work will pave the way for potential applications in areas including electronics and medicine, Ms. Olsson said.
Pierre Agostini is an emeritus professor at Ohio State University.
Ferenc Krausz is director at the Max Planck Institute of Quantum Optics in Germany and a professor of experimental physics at Ludwig Maximilian University of Munich.
Anne L’Huillier is a professor at Lund University in Sweden.

The laureates’ contributions have enabled the investigation of processes so rapid that they were “previously impossible to follow,” it added.The laureates’ contributions have enabled the investigation of processes so rapid that they were “previously impossible to follow,” it added.
“Through their experiments, this year’s laureates have created flashes of light that are short enough to take snapshots of electrons’ extremely rapid movements,” the committee said in a news release.
“Anne L’Huillier discovered a new effect from laser light’s interaction with atoms in a gas. Pierre Agostini and Ferenc Krausz demonstrated that this effect can be used to create shorter pulses of light than were previously possible.”
The prize went to John Clauser, Alain Aspect and Anton Zeilinger for independent works exploring quantum weirdness.The prize went to John Clauser, Alain Aspect and Anton Zeilinger for independent works exploring quantum weirdness.
On Monday, the prize in Physiology or Medicine went to Katalin Karikó and Drew Weissman for a chemical modification to messenger RNA. Their research led to the successful development of the Covid-19 vaccine and saved millions of lives. Dr. Karikó is the 13th woman to win the Nobel Prize in this category.On Monday, the prize in Physiology or Medicine went to Katalin Karikó and Drew Weissman for a chemical modification to messenger RNA.
