Ultrafast X-ray-induced dephasing of valence electrons
J. Vonka, B. Pedrini, J. Ravnik +14
Diffract-before-destroy schemes for atomic-scale electron mapping assume that ultrashort X-ray pulses outrun radiation damage. Although atomic cores move over tens of femtoseconds,…

Spin waves excited by hard x-ray transient gratings
Peter R. Miedaner, Alexei A. Maznev, Mykola Biednov +49
Recent progress in ultrafast x-ray sources helped establish x-rays as an important tool for probing lattice and magnetic dynamics initiated by femtosecond optical pulses. Here, we…
