The Nobel Prize in Physics was awarded to Pierre Agostini, Ferenc Krausz and Anne L’Huillier on Tuesday for experiments that “gave humanity new tools to explore the world of electrons inside atoms and molecules.”
Their work, the team said, is about “experimental methods for generating attosecond pulses of light for the study of electron dynamics in matter.”
At a press conference on Tuesday, Eva Olsen, chair of the Nobel Committee for Physics, said that “attosecond science allows us to address fundamental questions” such as the duration of the photoelectric effect, which earned Albert Einstein the 1921 physics Nobel.
An attosecond is one millionth of a trillionth of a second. According to the Royal Swedish Academy of Sciences, which awards the physics prize, the number of them per second is the same as the number of seconds that have passed since the universe began 13.8 billion years ago.
The work of the three laureates will pave the way for potential applications in fields including electronics and medicine, Ms. Olsen said.
Who are the winners?
Pierre Agostini is a Distinguished Professor at Ohio State University.
Ferenc Krausz is Director at the Max Planck Institute of Quantum Optics in Germany and Professor of Experimental Physics at the Ludwig Maximilian University of Munich.
Anne L’Huillier is a professor at Lund University in Sweden.
Why did the team say they were getting a prize?
“Pierre Agostini, Ferenc Krausz and Anne L’Huillier have demonstrated a way to generate very short pulses of light that can be used to measure rapid processes in which electrons move or transfer energy,” the awarding committee said.
It added that the laureates’ contributions enabled the investigation of processes to become more rapid and which were “previously impracticable”.
What impact did their work have?
“Through their experiments, this year’s laureates have generated flashes of light sufficient to capture snapshots of the extremely fast movements of electrons,” the team said in a news release.
“Anne L’Hullier discovered a new effect through the interaction of laser light with atoms in a gas. Pierre Agostini and Ferenc Krausz demonstrated that this effect could be used to produce shorter pulses of light than had previously been possible.
Who will win the Nobel Prize in Physics in 2022?
The prize went to John Glaser, Alain Aspecht and Anton Zeilinger for their independent work exploring quantum difference.
Who won the Nobel Prize in Science this year?
On Monday, the Prize in Physiology or Medicine went to Katelyn Carrico and Drew Weissman for chemical modification of messenger RNA. Their research led to the successful development of a Covid-19 vaccine and saved millions of lives. Dr Carrico is the 13th woman to win the Nobel Prize in this category.
