Nobel Prize in Physics goes to three laser flash researchers

As of: October 3rd, 2023 2:21 p.m

This year’s Nobel Prize in Physics was shared by Pierre Agostini, Ferenc Krausz and Anne L’Huillier for their research into the world of electrons in atoms and molecules. Krausz is director of the Max Planck Institute for Quantum Optics in Garching.

This year’s Nobel Prize in Physics goes to Pierre Agostini, Ferenc Krausz and Anne L’Huillier for their research in the field of electron dynamics, as announced by the responsible committee at the Karolinska Institute in Stockholm.

Agostini works at France’s Aix-Marseille University, L’Huillier at Sweden’s University of Lund. The Austro-Hungarian physicist Krausz conducts research at the Ludwig Maximilians University in Munich and is director of the Max Planck Institute for Quantum Optics in Garching.

Research in the attosecond range

Specifically, the award is about “experimental methods for generating attosecond light pulses for the study of electron dynamics in matter.” The researchers generated attosecond light pulses that are short enough to take snapshots of the extremely fast movements of the electrons, the academy said.

L’Huillier discovered a new effect through the interaction of laser light with atoms in a gas. Agostini and Krausz showed that this effect could be used to produce shorter flashes of light than was previously possible.

An attosecond is one billionth of a billionth of a second – this corresponds to the ratio of one second to the age of the universe.

Krausz didn’t expect any awards

Krausz, who works in Bavaria, was very surprised by the news of the award. “I’m trying to realize that this is reality and not a dream,” Krausz told the dpa news agency shortly after the award was announced. He didn’t expect that.

With his research, together with many scientists and teams, he managed to “follow in real time the fastest processes that exist in nature outside the atomic nucleus, namely the movement of electrons,” said Krausz at the Max Planck Institute. which just had an open day. “These movements initiate all molecular processes in living organisms and are ultimately responsible for the development of diseases at the most fundamental level.”

Findings in this area could therefore be important for medicine. There has been a large research project involving 10,000 people for three years to detect diseases such as cancer in the early stages. They regularly have blood samples taken, which are examined with infrared laser light – in order “to obtain further information that laboratory medicine cannot currently provide us about diseases that may develop at an earlier stage.” The initial results are promising, but it will probably take another five to ten years before application.

Call during a Course

Prize winner L’Huillier received the famous call from Stockholm during a course. “I taught,” said the French nuclear physicist when asked where she had been reached to tell her about the award shortly before it was announced. She was only able to answer the call on the third or fourth attempt during a break. The last half hour of her lecture was “a little difficult,” she said when she was connected by telephone to the award announcement in Stockholm.

The Nobel Prize means a lot to her, said L’Huillier. “It’s the most prestigious award and I’m so happy about it. Not that many women receive this award. It’s very, very special.”

Successor to Einstein and Curie

The Nobel Prize is endowed with eleven million Swedish crowns (around 950,000 euros) and is internationally considered one of the most important scientific awards. Last year, the French physicist Alain Aspect, the American experimental physicist John Clauser and the Austrian quantum physicist Anton Zeilinger were awarded the Nobel Prize in Physics for their work in the field of quantum mechanics.

The best-known recipients of the Nobel Prize in Physics are Albert Einstein, who received it in 1921 for his work on the photoelectric effect, and Marie Curie, who received the prize in 1903 for her work on radioactive radiation.
