Photo-induced plasmon-phonon coupling in PbTe
M. P. Jiang, M. Trigo, S. Fahy +19
We report the observation of photo-induced plasmon-phonon coupled modes in the group IV-VI semiconductor PbTe using Fourier-transform inelastic X-ray scattering at the Linac Cohere…
Formation of buried domain walls in the ultrafast transition of SmTe
M. Trigo, P. Giraldo-Gallo, J. N. Clark +13
We study ultrafast x-ray diffraction on the charge density wave (CDW) of SmTe using an x-ray free electron laser. The CDW peaks show that photoexcitation with near-infrared pum…
Coherent order parameter dynamics in SmTe
M. Trigo, P. Giraldo-Gallo, M. E. Kozina +13
We present a combined ultrafast optical pump-probe and ultrafast x-ray diffraction measurement of the CDW dynamics in SmTe at 300 K. The ultrafast x-ray diffraction measurement…
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…
