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 ...
Optical properties of semiconductors via pump-probe experiments: statistical-thermodynamical approach, hot plasma and coherent phonon states

Polariton-driven phonon laser
(Nature, 2020-09)
Efficient generation of phonons is an important ingredient for a prospective electrically-driven phonon laser. Hybrid quantum systems combining cavity quantum electrodynamics and optomechanics constitute a novel platform ...
Spin-orbit coherent oscillations and phonon-induced spin relaxation in a quantum dot

Imaging of a patterned and buried molecular layer by coherent acoustic phonon spectroscopy
(American Institute Of Physics, 2012-11)
A molecular layer of aminopropyltriethoxysilane is patterned with a focused ion beam and subsequently covered by a gold film. The gold-polymer-substrate structures are afterwards imaged by ultrafast coherent acoustic phonon ...

Phonon maser stimulated by spin postselection
(American Physical Society, 2020-06-09)
In a sequence of single spins interacting longitudinally with a mechanical oscillator, and using the micromaser model with random injection, we show that after an appropriate postselection of each spin, a phonon laser ...
Tailored Hypersound Generation in Single Plasmonic Nanoantennas
(American Chemical Society, 2016-01)
Ultrashort laser pulses impinging on a plasmonic nanostructure trigger a highly dynamic scenario in the interplay of electronic relaxation with lattice vibrations, which can be experimentally probed via the generation of ...
