Imaging of Antiferroelectric Dark Modes in an Inverted Plasmonic Lattice
Javier Rodriguez Alvarez, Amilcar Labarta, Juan Carlos Idrobo +8
Plasmonic lattice nanostructures are of technological interest because of their capacity to manipulate light below the diffraction limit. Here, we present a detailed study of dark…
The Raman coupling function in amorphous silica and the nature of the long wavelength excitations in disordered systems
A. Fontana, R. Dell'Anna, M. Montagna +6
New Raman and incoherent neutron scattering data at various temperatures and molecular dynamic simulations in amorphous silica, are compared to obtain the Raman coupling coefficien…
High frequency sound waves in vitreous silica
R. Dell'Anna, G. Ruocco, M. Sampoli +1
We report a molecular dynamics simulation study of the sound waves in vitreous silica in the mesoscopic exchanged momentum range. The calculated dynamical structure factors are in…
Low-frequency Raman scattering in model disordered solids: percolators above threshold
O. Pilla, G. Viliani, R. DellAnna +1
The Raman coupling coefficients of site- and bond-percolators at concentration higher than percolation threshold are computed for two scattering mechanisms: Bond Polarizability (BP…
