Jakarta –
The winners of the 2023 Nobel Prize in Physics have been announced. Three scientists from the United States, Germany and Sweden won this award.
This year’s three Nobel Prize winners in physics were recognized for their experiments that provided new tools for humanity to explore the world of electrons in atoms and molecules. These scientists demonstrated a way to produce very short pulses of light, so they could be used to measure the rapid processes by which electrons move or change their energy.
2023 Nobel Prize Winner in Physics
The Royal Swedish Academy of Sciences awarded the 2023 Nobel Prize in Physics to:
Pierre Agostini: received PhD in 1968 from Aix-Marseille University, France. Currently a professor at Ohio State University, United States. Ferenc Krausz: received PhD in 1991 from Vienna University of Technology, Austria. Currently director at the Max Planck Institute of Quantum Optics and professor at Ludwig-Maximilians-Universitat Munchen, Germany. Anne L’Huillier: received PhD in 1986 from University Pierre and Marie Curie, Paris. Now a professor at Lund University, Sweden.
Quoted from the release of the official Nobel institution, in 1987 Anne L’Huillier discovered that there were many colors of reflected light that increased when she transmitted infrared laser light through noble gases.
This is because the laser light interacts with the atoms in the gas, giving the electrons more energy which is then emitted as light. Anne L’Huillier continued to explore this phenomenon and laid the foundation for subsequent breakthroughs.
Then in 2001 Pierre Agostini succeeded in producing and studying a series of light pulses where each pulse only lasted 250 attoseconds (1 attosecond = 1 x 10-18 seconds). At the same time, Ferenc Krausz was working on another type of experiment. Krausz’s research enabled the isolation of a single pulse of light that lasted 650 attoseconds.
“Now we can open the gates to the world of electrons. Attosecond physics gives us the opportunity to understand the mechanisms governed by electrons. The next step is to exploit them,” said Eva Olsson, Chair of the Nobel Committee for Physics.
There are various possible applications in various fields. In the field of electronics, for example, it is important to understand and control the behavior of electrons in a material. Attosecond pulses can also be used to identify different molecules, for example in medical diagnosis.
