Contra-Intuitive Features of Time-Domain Brillouin Scattering in Collinear Paraxial Sound and Light Beams
Vitalyi E. Gusev
Time-domain Brillouin scattering is an opto-acousto-optical probe technique for the evaluation of the transparent materials. Ultrashort pump laser pulses via optoacoustic conversio…
Resonant thermal energy transfer to magnons in a ferromagnetic nanolayer
Michal Kobecki, Alexey V. Scherbakov, Tetiana L. Linnik +7
Energy harvesting is a modern concept which makes dissipated heat useful by transferring thermal energy to other excitations. Most of the existing principles for energy harvesting…
On the magnetoelastic and magnetoelectric couplings across the antiferromagnetic transition in multiferroic BiFeO3
Mariusz Lejman, Charles Paillard, Vincent Juvé +7
Clear anomalies in the lattice thermal expansion (deviation from linear variation) and elastic properties (softening of the sound velocity) at the antiferromagnetic-to-paramagnetic…
Ultrafast tunable modulation of light polarization at terahertz frequencies
Vincent Juvé, Gwenaëlle Vaudel, Zoltan Ollmann +4
Controlling light polarization is one of the most essential routines in modern optical technology. Since the demonstration of optical pulse shaping by spatial light modulators and…
Granular Graphene: direct observation of zigzag and armchair edge waves
Li-Yang Zheng, Florian Allein, Vincent Tournat +2
We propose a mechanical granular graphene obtained by replacing the carbon atoms with macroscopic spherical stainless steel beads in contact. The experimental measured dispersion r…
