Three researchers, Pierre Agostini, Ferenc Krausz, and Anne L’Huillier, have been awarded the 2023 Nobel Prize in Physics for their work on studying electrons. They developed experimental methods that generate attosecond pulses of light to capture the movement and behavior of electrons inside atoms and molecules. This groundbreaking research has revolutionized how scientists study electrons and has the potential to lead to advancements in electronics and disease diagnoses. Anne L’Huillier is only the fifth woman to have ever won the Nobel Prize in Physics. The attosecond pulses of light can be used to make movies of electrons, allowing scientists to observe their rapid movements. The research has given humanity new tools to explore the world of electrons and has implications for medical diagnostics and electronics.
