Denser glasses relax faster: a competition between rejuvenation and aging during in-situ high pressure compression at the atomic scale
A. Cornet, G. Garbarino, F. Zontone +15
A fascinating feature of metallic glasses is their ability to explore different configurations under mechanical deformations. This effect is usually observed through macroscopic ob…
Directional lasing at high oblique angle from metasurface exhibiting multivalley dispersion
Hai Son Nguyen, Florian Dubois, Thierry Deschamps +5
We report on a metasurface laser emitting at the valley extremum of a multivalley energy-momentum dispersion. Such peculiar dispersion shape is obtained by hybridizing high quality…
Symmetry Breaking in Photonic Crystals: On-Demand Dispersion from Flatband to Dirac Cones
Hai Son Nguyen, Florian Dubois, Thierry Deschamps +6
We demonstrate that symmetry breaking opens a new degree of freedom to tailor the energy-momentum dispersion in photonic crystals. Using a general theoretical framework in two illu…
Blue light absorption enhancement based on vertically channelling modes in nano-holes arrays
Guillaume Gomard, Romain Peretti, Ségolène Callard +6
We investigate the specific optical regime occurring at short wavelengths, in the high absorption regime, in silicon thin-films patterned by periodically arranged nano-holes. Near-…
Poisson ratio and excess low-frequency vibrational states in glasses
Eugène Duval, Thierry Deschamps, Lucien Saviot
In glass, starting from a dependence of the Angell's fragility on the Poisson ratio [V. N. Novikov and A. P. Sokolov, Nature 431, 961 (2004)], and a dependence of the Poisson ratio…
Density hardening plasticity and mechanical aging of silica glass under pressure: A Raman spectroscopic study
Damien Vandembroucq, Thierry Deschamps, Camille Coussa +4
In addition of a flow, plastic deformation of structural glasses (in particular amorphous silica) is characterized by a permanent densification. Raman spectroscopic estimators are…
