Phonons in an Entropic Crystal
Physical Review Letters, 2000Hard spheres crystallize due to purely entropic forces. The underlying excluded-volume interaction is completely anharmonic and the nature of the phonon spectrum is therefore of interest. To measure the single-particle motion and the phonon spectrum by dynamic light scattering we have used a collection of novel techniques including multispeckle cross ...

Phononic Crystal with Adaptive Connectivity
Advanced Materials, 2013The band structure of a phononic crystal can be controlled by tuning the mechanical stiffness of the links connecting its constituting elements. The first implementation of a phononic crystal with adaptive connectivity is obtained by using piezoelectric resonators as variable stiffness elements, and its wave-propagation properties are experimentally ...

Phonon Spectrum in a Plasma Crystal
Physical Review Letters, 2002The Fourier spectra of longitudinal and transverse waves corresponding to random particle motion were measured in a two-dimensional plasma crystal. The crystal was composed of negatively charged microspheres immersed in a plasma at a low gas pressure.

PHONON-PHONON INTERACTION IN CRYSTALS
1963Abstract : The generation, propagation and interaction of phonons with emphasis on the phonon interaction in crystals were investigated. Several phonon phonon interaction processes in X-cut quartz, silicon and germanium were investigated. These involve forward traveling wave, backward traveling wave, frequency up conversion and harmonic generation ...

2012 European Frequency and Time Forum, 2008
A new acoustic microsensor principle is introduced for the first time. It is based on acoustic band gap materials, so-called phononic crystals. The sensor employs features of the band gap to determine properties of one component that builds the phononic crystal.

Phonon focusing in piezoelectric crystals
Physical Review B, 1987Phonon focusing in dielectric crystals depends upon the second-order elastic constants [1]. These constants determine the shape of the phase and group-velocity surfaces for each of the three modes and thus the phonon focusing properties of the crystal.
