Three scientists, one Nobel Prize, and the world of electrons, which is now a little closer to us.
Three scientists who actively studied the properties of electrons were awarded the 2023 Nobel Prize in Physics. Pierre Agostini, Ferenc Krause and Anne L'ouillier were recognized for their experiments that, in the words of the Nobel Committee, " provided humanity with new tools for exploring the world of electrons inside atoms and molecules." This was announced by the Royal Swedish Academy of Sciences.
Scientists from the United States, Germany and Sweden used extremely short pulses of light to track the movement of electrons in atoms and create the chemical bonds needed to form molecules. "All atoms are a nucleus surrounded by clouds of electrons, and it is these clouds of electrons that interact with each other to create molecules," said Robert Rosner, president of the American Physical Society.
Agostini is an Emeritus professor at Ohio State University, Krause holds positions at the Max-Planck Institute for Quantum Optics and Ludwig-Maximilian University of Munich, and L'Huillier is a professor at Lund University in Sweden. L'ouillier became the fifth woman to be awarded the Nobel Prize in Physics.
The works awarded this prize belong to the discipline known as attosecond physics. The term comes from the duration of light pulses used in experiments that lasted only an attosecond. Attosecond — a unit of time in the International System of Units, equal to 1 × 10⁻1⁸ seconds. For comparison, an attosecond with respect to a second is equal to a second with respect to about 31.71 billion years.
