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…
Nonlinear X-ray Compton Scattering
Matthias Fuchs, Mariano Trigo, Jian Chen +22
X-ray scattering is a weak linear probe of matter. It is primarily sensitive to the position of electrons and their momentum distribution. Elastic X-ray scattering forms the basis…
