Extreme ultraviolet transient gratings: A tool for nanoscale photoacoustics
L. Foglia, R. Mincigrucci, A. A. Maznev +23
Collective lattice dynamics determine essential aspects of condensed matter, such as elastic and thermal properties. These exhibit strong dependence on the length-scale, reflecting…
Observation of the massive Lee-Fukuyama phason in a charge density wave insulator
Soyeun Kim, Yinchuan Lv, Xiao-Qi Sun +10
The lowest-lying fundamental excitation of an incommensurate charge density wave (CDW) material is widely believed to be a massless phason -- a collective modulation of the phase o…
Ultrafast x-ray scattering reveals composite amplitude collective mode in the Weyl charge density wave material (TaSe)I
Quynh L. Nguyen, Ryan A. Duncan, Gal Orenstein +27
We report ultrafast x-ray scattering experiments of the quasi-1D charge density wave (CDW) material (TaSe)I following photoexcitation with femtosecond infrared laser pulses…
