Spinning Active Matter

Objective

Active-matter physics describes the mesmerizing dynamics of interacting motile bodies: from bird flocks and cell colonies, to collections of synthetic units independently driven far from equilibrium. Until now, however, all man-made realizations have been merely limited to 2D model systems. We will introduce a paradigm shift to upgrade the status of synthetic active matter from aesthetic 2D experiments to genuine 3D materials with unanticipated engineering applications.

The essential goal is to construct the first generation three-dimensional active materials assembled from colloidal spinners, and to lay out the foundations of spinning active matter.

I articulate my project around three complementary aims, all based on a unique experimental platform combining high-content microfluidics, smart colloidal design, optical tweezers, and high-speed confocal imaging:

Aim 1. Spinner Interactions.
We will introduce a versatile microfluidic platform to disentangle, tailor and elucidate the pair interactions which dictate the collective dynamics of colloidal spinners.

Aim 2. Frustration-induced (dis)order.
Building first on model experiments on spinning monolayers, we will explain how the intrinsic frustration of spinning motion at the microscopic scale shapes the macroscopic structure and flows of spinning matter.

Aim 3. Spinner liquids, solids and liquid crystals.
We will then be equipped to introduce the first generation of tree dimensionnal liquids, solids and liquid crystals assembled from synthetic active matter. Combining microfluidics and high-speed confocal imaging, we will establish their phase behavior and relate their inner microscopic dynamics to their macroscopic mechanical response.
