Sampling eigenmodes in colloidal solids
A. C. Maggs, M. Schindler
We study the properties of correlation matrices widely used in the characterisation of vibrational modes in colloidal materials. We show that the eigenvectors in the middle of the…
Microfluidic self assembly
Bingqing Shen, Joshua Ricouvier, Mathilde Reyssat +2
Recent progress in colloidal science has led to elaborate self-assembled structures whose complexity raises hopes for elaborating new materials. However, the throughputs are extrem…
Indentation of a Rigid Sphere into an Elastic Substrate with Surface Tension and Adhesion
Chung-Yuen Hui, Tianshu Liu, Thomas Salez +2
The surface tension of compliant materials such as gels provides resistance to deformation in addition to and sometimes surpassing that due to elasticity. This article studies how…
Two-phase flow in a chemically active porous medium
Alexandre Darmon, Michael Benzaquen, Thomas Salez +1
We study the problem of the transformation of a given reactant species into an immiscible product species, as they flow through a chemically active porous medium. We derive the equ…
Self-propulsion of pure water droplets by spontaneous Marangoni stress driven motion
Ziane Izri, Marjolein N. van der Linden, Sébastien Michelin +1
We report spontaneous motion in a fully bio-compatible system consisting of pure water droplets in an oil-surfactant medium of squalane and monoolein. Water from the droplet is sol…
Spectral density of the non-backtracking operator
Alaa Saade, Florent Krzakala, Lenka Zdeborová
The non-backtracking operator was recently shown to provide a significant improvement when used for spectral clustering of sparse networks. In this paper we analyze its spectral de…
