Effects of salinity on flows of dense colloidal suspensions
Marc Lagoin, Rémy Fulcrand, Agnès Piednoir +1
We experimentally study the effects of salt concentration on the flowing dynamics of dense suspensions of micrometer-sized silica particles in microfluidic drums. In pure water, th…
Brownian granular flows down heaps
Antoine Bérut, Olivier Pouliquen, Yoel Forterre
We study the avalanche dynamics of a pile of micrometer-sized silica grains in water-filled microfluidic drums. Contrary to what is expected for classical granular materials, avala…
Creeping Avalanches of Brownian Granular Suspensions
Antoine Bérut, Olivier Pouliquen, Yoel Forterre
We study the avalanche dynamics of a pile of micron-sized silica grains in miniaturized rotating drums filled with water. Contrary to what is expected for classical granular materi…
Energetics of a driven Brownian harmonic oscillator
Mohammad Yaghoubi, M. Ebrahim Foulaadvand, Antoine Bérut +1
We provide insights into energetics of a Brownian oscillator in contact with a heat bath and driven by an external unbiased time-periodic force that takes the system out of thermod…
Fluctuations in an aging system: absence of effective temperature in the sol-gel transition of a quenched gelatin sample
Antoine Bérut, Artyom Petrosyan, Juan Ruben Gomez-Solano +1
We study the fluctuations of a Brownian micro particle trapped with optical tweezers in a gelatin solution undergoing a fast local temperature quench below the sol-gel transition.…
Information and thermodynamics: Experimental verification of Landauer's erasure principle
Antoine Bérut, Artyom Petrosyan, Sergio Ciliberto
We present an experiment in which a one-bit memory is constructed, using a system of a single colloidal particle trapped in a modulated double-well potential. We measure the amount…
Simultaneous 3D measurement of the translation and rotation of finite size particles and the flow field in a fully developed turbulent water flow
Simon Klein, Mathieu Gibert, Antoine Bérut +1
We report a novel experimental technique that measures simultaneously in three dimensions the trajectories, the translation, and the rotation of finite size inertial particles toge…
