Ultrafast electron-phonon decoupling in graphite

K. Ishioka, M. Hase, M. Kitajima, L. Wirtz, A. Rubio, H. Petek

We report the ultrafast dynamics of the 47.4 THz coherent phonons of graphite interacting with a photoinduced non-equilibrium electron-hole plasma. Unlike conventional materials, upon photoexcitation the phonon frequency of graphite upshifts, and within a few picoseconds relaxes to the stationary…

Structural health monitoring using cross-correlation of an ambient noise field

Najib Abou Leyla, Emmanuel Moulin, Jamal Assaad, Sébastien Grondel, Pascal Poussot

Theoretical and experimental studies in underwater acoustic, seismology and more recently ultrasonic have demonstrated that an estimate of the Time Domain Green Function (TDGF) between two receivers could be obtained from the cross-correlation of a diffuse acoustic noise field of these two…

Collective acoustic modes in various two-dimensional crystals by ultrafast acoustics: theory and experiments

J.F. Robillard, Arnaud Devos, I. Roch-Jeune, P. A. Mante

We study the elastic properties of two-dimensional phononic crystals made of aluminum nanocube lattices. From the experimental point of view, collective modes resulting from the coupling between cubes inside the crystal are excited and time resolved using ultrafast acoustics. We derive a general…
