Machine learning applied to single-shot x-ray diagnostics in an XFEL
A. Sanchez-Gonzalez, P. Micaelli, C. Olivier +39
X-ray free-electron lasers (XFELs) are the only sources currently able to produce bright few-fs pulses with tunable photon energies from 100 eV to more than 10 keV. Due to the stoc…
Attosecond screening dynamics mediated by electron-localization
M. Volkov, S. A. Sato, F. Schlaepfer +6
Transition metals with their densely confined and strongly coupled valence electrons are key constituents of many materials with unconventional properties, such as high-Tc supercon…
Beyond a phenomenological description of magnetostriction
A. H. Reid, X. Shen, P. Maldonado +28
We use ultrafast x-ray and electron diffraction to disentangle spin-lattice coupling of granular FePt in the time domain. The reduced dimensionality of single-crystalline FePt nano…
Direct measurement of non-equilibrium phonon occupations in femtosecond laser heated Au films
T. Chase, M. Trigo, A. H. Reid +9
We use ultrafast electron diffraction to detect the temporal evolution of phonon populations in femtosecond laser-excited ultrathin single-crystalline gold films. From the time-dep…
