Aggregates relaxation in a jamming colloidal suspension after shear cessation
F. Ianni, D. Lasne, R. Sarcia +1
The reversible aggregates formation in a shear thickening, concentrated colloidal suspension is investigated through speckle visibility spectroscopy, a dynamic light scattering tec…
Drastic change in transport of entropy with quadrupolar ordering in PrFeP
A. Pourret, K. Behnia, D. Kikuchi +3
The antiferroquadrupolar ordering of PrFeP is explored by probing thermal and thermoelectric transport. The lattice thermal conductivity drastically increases with the…
Aging, memory and rejuvenation: some lessons from simple models
Florent Krzakala, Federico Ricci-Tersenghi
Many recent experiments probed the off equilibrium dynamics of spin glasses and other glassy systems through temperature cycling protocols and observed memory and rejuvenation phen…
Scale separation in granular packings: stress plateaus and fluctuations
C. Goldenberg, A. P. F. Atman, P. Claudin +2
It is demonstrated, by numerical simulations of a 2D assembly of polydisperse disks, that there exists a range (plateau) of coarse graining scales for which the stress tensor field…
Transverse Instability of Avalanches in Granular Flows down Incline
Igor S. Aranson, Florent Malloggi, Eric Clement
Avalanche experiments on an erodible substrate are treated in the framework of ``partial fluidization'' model of dense granular flows. The model identifies a family of propagating…
Meandering rivulets on a plane: a simple balance between inertia and capillarity?
Nolwenn Le Grand-Piteira, Adrian Daerr, Laurent Limat
Experiments on streams of water flowing down a rigid substrate have been performed for various plate inclinations and flow rates, and we focused on the regime of stationary meander…
