Orientational order on non-orientable domains
Gianmarco Spera, Axel Fotso Ndefo, Keaton J. Burns +1
We study the statistical properties of passive and active many-body systems with orientational degrees of freedom on non-orientable domains. By rephrasing topological constraints a…
Low-Pass Filtering of Active Turbulent Flows to Liquid Substrates
Gianmarco Spera, Julia M. Yeomans, Sumesh P. Thampi
To study the impact of active systems on their surroundings, we introduce a model that couples an active nematic fluid to an isotropic substrate fluid via friction. We numerically…
Contact Forces in Motility-Regulated Active Matter
Quan Manh Nguyen, Manh-Quan Nguyen, Alberto Dinelli +2
Long-range interactions are ubiquitous in nature, where they are mediated by diffusive fields at the cellular scale or by visual cues for groups of animals. Short-range forces, whi…
Fluctuation-Induced First Order Transition to Collective Motion
David Martin, Gianmarco Spera, Hugues Chaté +4
The nature of the transition to collective motion in assemblies of aligning self-propelled particles remains a long-standing matter of debate. In this article, we focus on dry acti…
