Ultrafast Dissipative Localization of Electronic Energy in AuPt Superlattices
C. Walz, M. Mattern, J. -E. Pudell +15
Controlling the spatial distribution of absorbed optical energy is central to nanoscale photothermal chemistry, plasmonics, and ultrafast materials control. Here, we show that a me…

Dynamical diffraction formalism for imaging time-dependent diffuse scattering from coherent phonons with Dark-Field X-ray Microscopy
Darshan Chalise, Brinthan Kanesalingam, Dorian P. Luccioni +3
Coherent acoustic phonons, whose damping sets the upper bound of quality factors in acoustic resonators, play a critical role in advanced telecommunication and quantum information…
