Limitations of Debye-Waller lattice temperature extraction under electronic excitation
N. Medvedev, M. Kopecky, J. Chalupsky +1
Ultrafast diffraction is the cutting-edge technique to extract the atomic temperature at femtosecond timescales, and further related quantities - in particular, electron-phonon cou…

The Darkfield Approach to Measuring Vacuum Birefringence and Light-by-Light Couplings -- A Proof-of-Principle Experiment
Michal SmÃd, Pooyan Khademi, Carsten Bähtz +29
Vacuum fluctuations give rise to effective nonlinear interactions between electromagnetic fields. These generically modify the characteristics of light traversing a strong-field re…

Shake-off in XFEL heated solid density plasma
G. O. Williams, L. Ansia, M. Makita +25
In atoms undergoing ionisation, an abrupt re-arrangement of free and bound electrons can lead to the ejection of another bound electron (shake-off). The spectroscopic signatures of…
