Nobel Prize in Physics

On Tuesday, a Nobel Prize in physics was awarded to three researchers for providing an unprecedented, albeit fleeting, insight into the exceedingly rapid realm of spinning electrons. This area of study holds promise for advancements in electronics and medical diagnostics.

The distinguished recipients of the award are Anne L’Huillier, a French-Swedish physicist; Pierre Agostini, a French scientist; and Hungarian-born Ferenc Krausz. Their pioneering work focuses on electrons, subatomic particles that orbit the nucleus of an atom and play a critical role in multiple domains, including chemistry, physics, biological systems, and technology.

Electrons have hitherto eluded human efforts at isolation due to their incredibly high speeds. However, the scientists have now captured a “blurry” snapshot of these particles by observing them in the minutest fraction of a second conceivable, thus paving the way for new scientific avenues.

Mats Larsson, a member of the Nobel Committee, emphasized the significance of understanding and controlling electrons, stating, “Gaining such control and understanding constitutes a major leap forward.”

Other notable Nobel Prize recipients include Karikó and Weissman, who were honored in medicine for enabling the development of mRNA vaccines against COVID-19.

Anne L’Huillier, affiliated with Lund University in Sweden, is the fifth female physicist to be honored with a Nobel Prize. She encouraged women interested in the field, stating during an interview with The Big Big News, “If you possess even a modicum of passion for challenges like this, then pursue it.”

What Led to the Nobel-Worthy Discovery?

Employing increasingly faster laser pulses, the scientists were able to capture atomic activity that occurs within an attosecond, or one quintillionth of a second. This rapidity is analogous to how photographers use high-speed shutter technology to photograph rapidly moving subjects, like a hummingbird in mid-flight.

To provide perspective on the duration of an attosecond, Eva Olsson, chair of the Nobel Committee, suggested imagining one second—the time it takes for a heart to beat—divided by 1,000 six times over. Mark Pearce, another Nobel Committee member, added that the number of attoseconds in a single second is equivalent to the number of seconds that have elapsed since the Big Bang approximately 13.8 billion years ago.

Why Electrons Are Crucial

Electrons are essential in facilitating chemical bonds between atoms, as they are the adhesive that enables the formation of molecules. These molecules, in turn, are the fundamental building blocks of all living organisms. Ferenc Krausz underscored their ubiquity in both our biological and technological existence during a press conference.

The current focus of this area of science is foundational, aimed at enhancing our understanding of the universe. However, there are aspirations for its future practical applications in electronics, disease diagnostics, and elementary chemistry.

L’Huillier highlighted the importance of foundational science, stating that it took three decades of her work before the real-world applications of her research began to emerge.

Reactions from the Laureates

Upon receiving the news of her win, L’Huillier was in the midst of lecturing to undergraduates at Lund University. She returned to her teaching duties even after learning of her prestigious accolade, emphasizing her commitment to education.

Pierre Agostini, an emeritus professor at Ohio State University, was in Paris at the time of the announcement and was initially unreachable by the Nobel Committee.

Ferenc Krausz, affiliated with the Max Planck Institute of Quantum Optics and Ludwig Maximilian University of Munich, expressed his astonishment and elation at receiving the prize. Both Krausz and L’Huillier had previously won the esteemed Wolf prize in physics for their contributions, shared with Paul Corkum of the University of Ottawa.

The Nobel Prizes come with a cash reward of 11 million Swedish kronor (approximately $1 million), sourced from a bequest by the prize’s founder, Swedish inventor Alfred Nobel.

The announcement of the physics prize followed the previous day’s revelation that two scientists had received the Nobel Prize in medicine for work that enabled the production of mRNA vaccines against COVID-19.

The news was reported by journalists from various international locations, including Washington, Paris, The Hague, Copenhagen, and Berlin. For further information on the Nobel Prizes, visit the Big Big News website.

Frequently Asked Questions (FAQs) about Nobel Prize in Physics

Who are the winners of the 2023 Nobel Prize in Physics?

The 2023 Nobel Prize in Physics was awarded to Anne L’Huillier, Pierre Agostini, and Ferenc Krausz for their pioneering work on capturing a brief glimpse into the fast-spinning world of electrons.

What is the significance of their research?

The research provides the first-ever “blurry” view of spinning electrons, which are fundamental to a broad range of sciences and technologies, from chemistry and physics to medical diagnostics and electronics. The work has the potential to lead to significant advancements in these fields.

What techniques did the scientists use for their discovery?

The scientists employed ultra-fast laser pulses to observe atomic action occurring at dizzying speeds—specifically, in timeframes as short as one quintillionth of a second, known as an attosecond.

Why are electrons important?

Electrons are critical for atomic binding and chemical reactions. They are omnipresent in both biological and technological aspects of our lives. Understanding their movement can potentially lead to advancements in various scientific and practical applications.

How did Anne L’Huillier react to winning the Nobel Prize?

Anne L’Huillier was teaching a class when she received the news of her win. Despite the significance of the moment, she chose to finish her lecture before attending to the Nobel-related news conference. She emphasized the importance of women pursuing challenges in the field of physics.

What is an attosecond and how does it relate to the research?

An attosecond is one quintillionth of a second. To provide some context, there are as many attoseconds in a second as there have been seconds since the Big Bang, approximately 13.8 billion years ago. The researchers used this extremely small unit of time to capture the rapid movement of electrons.

Is there any potential for real-world applications of this research?

While the primary focus currently is on understanding fundamental aspects of our universe, there is hope that this research will eventually find practical applications in areas like electronics, disease diagnosis, and basic chemistry.

Who were the other notable winners of Nobel Prizes this year?

The Nobel Prize in Medicine was awarded for work enabling the creation of mRNA vaccines against COVID-19. The specific recipients were Karikó and Weissman.

How much is the cash award for the Nobel Prize?

The Nobel Prizes come with a cash award of 11 million Swedish kronor, which is approximately equivalent to $1 million USD.

Were there any other scientists who could have been included in this Nobel Prize win?

Ferenc Krausz mentioned that it was a shame the Nobel Prizes are limited to only three winners, as Paul Corkum, a scientist from the University of Ottawa, was also crucial to how the ultra-fast laser pulses could be measured.
