文摘
We show that broadband X-ray pulses can create wavepackets of valence electrons and holes localized in the vicinity of a selected atom (nitrogen, oxygen, or sulfur in cysteine) by stimulated resonant Raman scattering. The subsequent dynamics reveals highly correlated motions of entangled electron and hole quasiparticles. This information goes beyond the time-dependent total charge density derived from X-ray diffraction.
