Topology of pulsating active matter: Defect asymmetry controls emergent motility
Luca Casagrande, Alessandro Manacorda, Ãtienne Fodor
In pulsating active matter, topological defects are motile despite the absence of any macroscopic flows and microscopic self-propulsion. We reveal that this motility arises from a…
Hydrodynamics of pulsating active liquids
Tirthankar Banerjee, Thibault Desaleux, Jonas Ranft +1
Inspired by dense contractile tissues, where cells are subject to periodic deformation, we formulate and study a generic hydrodynamic theory of pulsating active liquids. Combining…
Contraction waves in pulsating active liquids: From pacemaker to aster dynamics
Tirthankar Banerjee, Thibault Desaleux, Jonas Ranft +1
We propose a hydrodynamic theory to examine the emergence of contraction waves in dense active liquids composed of pulsating deformable particles. Our theory couples the liquid den…
Control of active field theories at minimal dissipation
Artur Soriani, Elsen Tjhung, Ãtienne Fodor +1
Advances in experimental techniques enable the precise manipulation of a large variety of active systems, which constantly dissipate energy to sustain nonequilibrium phenomena with…
