Experimental demonstration of attosecond pump–probe spectroscopy with an X-ray free-electron laser
Pump–probe experiments with subfemtosecond resolution are the key to understanding electronic dynamics in quantum systems. Here we demonstrate the generation and control of subfemtosecond pulse pairs from a tw...

Open AccessObservation of site-selective chemical bond changes via ultrafast chemical shifts
The concomitant motion of electrons and nuclei on the femtosecond time scale marks the fate of chemical and biological processes. Here we demonstrate the ability to initiate and track the ultrafast electron re...

Open AccessGhost-imaging-enhanced noninvasive spectral characterization of stochastic x-ray free-electron-laser pulses
High-intensity ultrashort X-ray free-electron laser (XFEL) pulses are revolutionizing the study of fundamental nonlinear x-ray matter interactions and coupled electronic and nuclear dynamics. To fully exploit ...

Direct observation of coherent femtosecond solvent reorganization coupled to intramolecular electron transfer
It is well known that the solvent plays a critical role in ultrafast electron-transfer reactions. However, solvent reorganization occurs on multiple length scales, and selectively measuring short-range solute–...

Open AccessThe role of transient resonances for ultra-fast imaging of single sucrose nanoclusters
Intense x-ray free-electron laser (XFEL) pulses hold great promise for imaging function in nanoscale and biological systems with atomic resolution. So far, however, the spatial resolution obtained from single ...
