Disentangling charge and structural contributions during coherent atomic motions studied by ultrafast resonant x-ray diffraction
L. Rettig, A. Caviezel, S. O. Mariager +20
We report on the ultrafast dynamics of charge order and structural response during the photoinduced suppression of charge and orbital order in a mixed-valence manganite. Employing…

Ultrafast x-ray diffraction of a ferroelectric soft mode driven by broadband terahertz pulses
S. Grübel, J. A. Johnson, P. Beaud +14
Intense, few-cycle pulses in the terahertz frequency range have strong potential for schemes of control over vibrational modes in solid-state materials in the electronic ground-sta…
