"This is a world beyond the limits of human perception where matter is determined, where combinations of particles make up all the substances in the universe. There are events that occur in attoseconds (as), a trillionth of a second. An attosecond is equivalent to 0.000000000000000000001 second or 1x10-18 of a second and corresponds, approximately, to the time it takes light to pass through an atom and the natural scale of electronic motion in matter."
"The Hungarian Ferenc Krausz, the Frenchwoman Anne L'Huillier and Frenchman Pierre Agostini were awarded the Nobel Prize in Physics in 2023 for developing extremely brief pulses of light to measure the hitherto immeasurable process of the movement or exchange of energy of electrons. They received it eight months after this research obtained the BBVA Foundation's Frontiers of Knowledge Award in the Basic Sciences category."
"The Young Researcher Award in Experimental Physics has gone to Allan Johnson, Ramon y Cajal scientist at IMDEA Nanoscience Institute for his experiments generating ultrafast pulses of light the compass for discovering a world where what we know begins to take shape, enabling the study of materials, the understanding of the quantum universe, and even the observation of the body's cells in an unprecedented dimension."
Everyday events occur far more slowly than microscopic events, where matter is determined by particle combinations and electronic motion occurs on attosecond timescales. An attosecond (1×10−18 s) approximates the time light needs to cross an atom and matches the natural scale of electronic motion. ICFO produced a 19.2-attosecond soft X-ray pulse. Ferenc Krausz, Anne L'Huillier and Pierre Agostini received the 2023 Nobel Prize in Physics for creating ultrashort light pulses to measure electron energy movement, following recognition by the BBVA Foundation. The BBVA Foundation and RSEF awarded the Young Researcher in Experimental Physics to Allan Johnson for experiments generating ultrafast light pulses that enable studies of materials, quantum phenomena, and cellular observations.
