Ultrafast core-level spectroscopy reveals elusive precursors of exciton condensation in quantum materials

Many fascinating phases in quantum materials emerge when electrons, atoms and other microscopic components begin to act collectively. But these phases do not necessarily appear out of nowhere when a material crosses a transition temperature. Before long-range order develops,…
