Dynamical theory of topological defects II: Universal aspects of defect motion
Jacopo Romano, Benoît Mahault, Ramin Golestanian
We study the dynamics of topological defects in continuum theories governed by a free energy minimization principle, building on our recently developed framework [Romano J, Mahault…
Energetic cost of microswimmer navigation: the role of body shape
Lorenzo Piro, Andrej Vilfan, Ramin Golestanian +1
We study the energetic efficiency of navigating microswimmers by explicitly taking into account the geometry of their body. We show that, as their shape transitions from prolate to…
Dynamical pattern formation without self-attraction in quorum-sensing active matter: the interplay between nonreciprocity and motility
Yu Duan, Jaime Agudo-Canalejo, Ramin Golestanian +1
We study a minimal model involving two species of particles interacting via quorum-sensing rules. Combining simulations of the microscopic model and linear stability analysis of th…
Dynamical theory of topological defects I: the multivalued solution of the diffusion equation
Jacopo Romano, Benoît Mahault, Ramin Golestanian
Point-like topological defects are singular configurations that occur in a variety of in and out of equilibrium systems with two-dimensional orientational order. As they are associ…
Reentrant condensation transition in a model of driven scalar active matter with diffusivity edge
Jonas Berx, Aritra Bose, Ramin Golestanian +1
The effect of a diffusivity edge is studied in a system of scalar active matter confined by a periodic potential and driven by an externally applied force. We find that this system…
