Collective Effects
& Soft Matter

Home

EC2M studies all sorts of collective effects in soft matter :
mechanical properties — elasticity, rheology — glass transition- jamming, self-assembling, [emergence of collective motions, ... EC2M deals with colloids, emulsions, liquid crystals, granular media, active matter ...

EC2M is a team lead by Olivier Dauchot inside Gulliver, the CNRS Unit 7083. The team relies on the expertise in microfluidic of MMN and interact strongly with the theoretician of PCT.

Research Topics

Active Matter

This emerging interdisciplinary field encompasses the study of a large variety of systems, the individual components of which have the ability to transform energy into some kind of work. The source of energy can be of chemical but also of (...)


Liquid crystal shells

The design of colloidal objects capable of reproducing the directional interaction of atoms is currently a major challenge in colloidal science and nanotechnology. However, we are still far from having a robust method for producing colloidal (...)


Glass Transition and Jamming

In a loose sense, jamming describes many situations - from clogging silo to traffic jams - in which a set of particles gets trapped in a disordered configuration and stops flowing. This behavior is reminiscent of a supercooled liquid when (...)
