Micro-slips inside a granular shear band as nano-earthquakes

Autor: Houdoux, David, Amon, Axelle, Marsan, David, Weiss, Jérôme, Crassous, Jérôme

We study experimentally the fluctuations of deformation along a shear fault naturally emerging within a compressed frictional granular medium. Using laser interferometry, we show that the deformation inside this granular gouge occurs as a succession

International audience; Memory effects in seismology-such as the occurrence of aftershock sequences-are implicitly assumed to be governed by the time since the main event. However, experiments are yet to identify if memory effects are structural or t

It is a difficult task to obtain “twin atoms”, i.e. pairs of massive particles such that one can perform experiments in the same fashion that is routinely done with “twin photons”. One possible route to obtain such pairs is by dissociating ho

Water molecules were used to probe the physical and chemical properties of a model hydrophilic organic organized layer. To this end, H2O adsorption on mercaptoundecanoic acid self-assembled monolayers (SAMs) was investigated at the molecular level un
