Time-domain extreme ultraviolet diffuse scattering spectroscopy of nanoscale surface phonons
F. Capotondi, A. Maznev, F. Bencivenga +18
We report the observation of dynamic fringe patterns in the diffuse scattering of extreme ultraviolet light from surfaces, following femtosecond optical excitation. At each point o…
Hard X-ray Generation and Detection of Nanometer-Scale Localized Coherent Acoustic Wave Packets in SrTiO and KTaO
Yijing Huang, Peihao Sun, Samuel W. Teitelbaum +21
We demonstrate that the absorption of femtosecond x-ray pulses can excite quasi-spherical high-wavevector coherent acoustic phonon wavepackets using an all x-ray pump and probe sca…
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…
