Not just electrons. Not just fast.
Attosecond science is often told as a story about speed — the shortest pulses, the fastest electrons. Its real reach is wider: the properties of materials and the course of chemical reactions are set by the many-body interaction of electrons, holes and nuclei, and attosecond science now opens an entirely new view into it.
We watch matter choose its path.
Charge, spin, lattice motion, nuclei and collective fluctuations exchange energy, information and entropy while a material transforms or a molecule reacts. Driven from a single starting point, a system can end in different phases.
The mean field tells us which pathways are open. The fluctuations around it — the shot-to-shot variance — tell us which one the system takes. Reading both at once turns noise from a nuisance into a signal, and lets us see the choice happen in real time.
We develop and apply new methods to hard problems in quantum matter.
