SPLW01 - Building a bridge between non-equilibrium statistical physics and biology

Hydraulics consists in controlling fluid flows in networks of pipes and channels. After eight millennia of fundamental and applied research, we know that the laminar flows of viscous liquids are fully determined by the channel-network geometry, and by the location of the pumps and pressure sources needed to power fluid motion. However, over the past decade, we have learned how to engineer active fluids actuated from within. Countless experiments and theories have demonstrated their spontaneous laminar flows in isolated channels. But, the emergent flows of active fluids filling interconnected channel networks remains virtually uncharted and poorly understood. I will show how to e lay out the primary laws of active hydraulics and how active flows in channel networks realize dynamical spin ices.
