The recipients share the prize for "pioneering and novel work in the fields of ultrafast laser science and attosecond physics and for demonstrating time-resolved imaging of electron motion in atoms, molecules, and solids."
Anne L'Huillier is a professor of Atomic Physics at Lund University. In her research, Anne L'Huillier uses laser technology to create ultra-short light pulses that make it possible to peek into the microcosm. The pulses are unbelievably short: an attosecond is a billionth of a billionth of a second.
With these "camera flashes" it is possible to study the movements of electrons inside atoms and molecules. Her research group conducts experiments that provide a new basic scientific understanding of the dynamics inside the atoms, for example when an atom is ionized.
