Stochastic Forces Enhance Tracer Diffusion in Non-motile Active Matter
Henry Alston, Raphael Voituriez, Thibault Bertrand
Stochasticity is a defining feature of the pairwise forces governing interactions in biological systems-from molecular motors to cell-cell adhesion-yet its consequences on large-sc…

Disordered Yet Directed: The Emergence of Polar Flocks with Disordered Interactions
Eloise Lardet, Raphaël Voituriez, Silvia Grigolon +1
Flocking is a prime example of how robust collective behavior can emerge from simple interaction rules. The flocking transition has been studied extensively since the inception of…

Integer defects, flow localization, and bistability on curved active surfaces
Rushikesh Shinde, Raphaël Voituriez, Andrew Callan-Jones
Biological surfaces, such as developing epithelial tissues, exhibit in-plane polar or nematic order and can be strongly curved. Recently, integer (+1) topological defects have been…
