Ductile-to-brittle transition and yielding in soft amorphous materials: perspectives and open questions
Thibaut Divoux, Elisabeth Agoritsas, Stefano Aime +37
Soft amorphous materials are viscoelastic solids ubiquitously found around us, from clays and cementitious pastes to emulsions and physical gels encountered in food or biomedical e…
Characterization of ejecta in shock experiments with multiple light scattering
J. A. Don Jayamanne, J. -R. Burie, O. Durand +2
Upon impact, the free surface of a solid metal may eject a cloud of fast and fine particles. Photon Doppler Velocimetry (PDV) is one of the optical diagnostics used to characterize…
Sociohydrodynamics: data-driven modelling of social behavior
Daniel S. Seara, Jonathan Colen, Michel Fruchart +3
Living systems display complex behaviors driven by physical forces as well as decision-making. Hydrodynamic theories hold promise for simplified universal descriptions of socially-…
Purity-dependent Lorenz number, electron hydrodynamics and electron-phonon coupling in WTe
Wei Xie, Feng Yang, Liangcai Xu +3
We present a study of electrical and thermal transport in Weyl semimetal WTe down to 0.3 K. The Wiedemann-Franz law holds below 2 K and a downward deviation starts above. The d…
Dynamical Facilitation Governs the Equilibration Dynamics of Glasses
Rahul N. Chacko, François P. Landes, Giulio Biroli +3
Convincing evidence of domain growth in the heating of ultrastable glasses suggests that the equilibration dynamics of super-cooled liquids could be driven by a nucleation and grow…
Suppression of the Talbot effect in Fourier transform acousto-optic imaging
Maïmouna Bocoum, François Figliolia, Jean-Pierre Huignard +2
We report on the observation and correction of an imaging artifact attributed to the Talbot effect in the context of acousto-optic imaging using structured acoustic waves. When ult…
