Dynamical patterns and nonreciprocal effective interactions in an active-passive mixture through exact hydrodynamic analysis
James Mason, Robert L. Jack, Maria Bruna
The formation of dynamical patterns is one of the most striking features of nonequilibrium physical systems. Recent work has shown that such patterns arise generically from forces…

Convergence of a finite volume scheme for a model for ants
Maria Bruna, Markus Schmidtchen, Oscar de Wit
We develop and analyse a finite volume scheme for a nonlocal active matter system known to exhibit a rich array of complex behaviours. The model under investigation was derived fro…

Argentine ants regulate traffic flow with stopped individuals
Ulrich Dobramysl, Simon Garnier, Laure-Anne Poissonnier +2
We investigated the emerging traffic patterns of Argentine ants (Linepithema humile) as they navigated a narrow bridge between their nest and a food source. By tracking ant movemen…
