Physics Prize: Development of auto-second pulses for studying electrodynamics in matter
The Physics Prize was awarded to Pierre Agostini, Ferrence Krauss, and Anne Luele for their work in developing experimental methods that generate auto-second pulses of light. Auto-second pulses, which are extremely short bursts of light lasting 10^-18 seconds, allow physicists to study the movement of electrons around atoms. This research has revolutionized our understanding of electron behavior and has the potential to provide insights into the properties of materials and phenomena such as photosynthesis.
