Band gaps of acoustic waves propagating in a solid/liquid phononic fibonacci structure
(Elsevier, 2010-09-01)
Ultrafast generation of optical and acoustic phonons in nanocrystallites
(Society of Photo-Optical Instrumentation Engineers, 2005-12)
We report on the impulsive generation of optical and acoustic phonons in CdTe0.68Se0.32 nanocrystallites embedded in glass, at room temperature. Using ultrafast laser pulses in a pump-probe configuration, we were able to ...

Strong Optical-Mechanical Coupling in a Vertical GaAs/AlAs Microcavity for Subterahertz Phonons and Near-Infrared Light
(American Physical Society, 2013-01)
We show that distributed Bragg reflector GaAs/AlAs vertical cavities designed to confine photons are automatically optimal to confine phonons of the same wavelength, strongly enhancing their interaction. We study the ...
Acoustic phonons in superlattices

Disorder-free weak dynamic localization in deformable lattices
(Institute of Physics Publishing, 2018)
© 2018 IOP Publishing Ltd.We study the electron transport in a deformable lattice modeled in the semiclassical approximation as a discrete nonlinear elastic chain where acoustic phonons are in thermal equilibrium at ...
