Three researchers were awarded the 2023 Nobel Prize in physics for their groundbreaking work in studying electrons using attosecond-long flashes of light. These infinitesimally short light pulses have enabled scientists to observe rapid electron movements, especially during processes like the breaking of chemical bonds.
An attosecond is incredibly small when compared to a second. Credit: ©Johan Jarnestad/The Royal Swedish Academy of Sciences. One thousand attoseconds are in 1 femtosecond. But researchers couldn’t see movement on the electron scale until they could generate attosecond light pulses – electrons move too fast for scientists to parse exactly what they are up to at the femtosecond level.
