Itinerant and localized magnetization dynamics in antiferromagnetic Ho
L. Rettig, C. Dornes, N. Thielemann-Kuehn +12
Using femtosecond time-resolved resonant magnetic x-ray diffraction at the Ho L3 absorption edge, we investigate the demagnetization dynamics in antiferromagnetically ordered metal…
Watching coherent molecular structural dynamics during photoreaction: beyond kinetic description
Henrik T. Lemke, Kasper Skov Kjær, Robert Hartsock +11
A deep understanding of molecular photo-transformations is challenging because of the complex interaction between the configurations of electrons and nuclei. An initial optical exc…
Photoinduced suppression of the ferroelectric instability in PbTe
M. P. Jiang, M. Trigo, S. Fahy +18
The interactions between electrons and phonons drive a large array of technologically relevant material properties including ferroelectricity, thermoelectricity, and phase-change b…
How to distinguish squeezed and coherent phonons in femtosecond x-ray diffuse scattering
T. Henighan, M. Trigo, M. Chollet +9
Impulsive optical excitation can generate both coherent and squeezed phonons. The expectation value of the phonon displacement oscillates at the mode frequency for the cohe…
Generation of high-frequency strain waves during femtosecond demagnetization of Fe/MgO films
T. Henighan, M. Trigo, S. Bonetti +22
We use femtosecond time-resolved hard x-ray scattering to detect coherent acoustic phonons excited during ultrafast laser demagnetization of bcc Fe films. We determine the lattice…
Phonon Spectroscopy with Sub-meV Resolution by Femtosecond X-ray Diffuse Scattering
Diling Zhu, Aymeric Robert, Tom Henighan +5
We present a reconstruction of the transverse acoustic phonon dispersion of germanium from femtosecond time-resolved x-ray diffuse scattering measurements at the Linac Coherent Lig…
