Colloidal nanocrystals are successfully used as nanoscale building blocks for creating
hierarchical solids with structures that range from amorphous networks to sophisticated …

In the past 20 years, we have reached a broad understanding of many light-driven
phenomena in nanoscale systems. The temporal dynamics of the excited states are instead …

Abstract Metamaterials,,,, are artificial materials that exhibit unusual properties for
electromagnetic and sound waves. The quanta, namely photons and phonons, of these …

Converted into mechanical nanoresonators after optical pulsed excitation and electron
decay into coherent acoustic phonons, plasmonic nanoantennas produce a periodic …

We present a free-running 80-MHz dual-comb polarization-multiplexed solid-state laser
which delivers 1.8 W of average power with 110-fs pulse duration per comb. With a high …

Plasmonic coupling between adjacent metallic nanoparticles can be exploited for acousto-
plasmonics, single-molecule sensing, and photochemistry. Light absorption or electron …

The phonon properties of films fabricated from colloidal semiconductor nanocrystals play a
major role in thermal conductance and electron scattering, which govern the principles for …

We report real-space, time-resolved imaging of coherently excited acoustic phonon modes
in plasmonic nanoparticles via femtosecond electron imaging with an ultrafast electron …

Acoustic vibrations of assemblies of gold nanoparticles were investigated using ultralow
frequency micro-Raman scattering and finite element simulations. When exciting the …

We explore the influence of the nanoporous structure on the thermal relaxation of electrons
and holes excited by ultrashort laser pulses (∼ 7 fs) in thin gold films. Plasmon decay into …
