Moving against the odds with a cyclic active Brownian ratchet: current enhancement and reversal
Theo Spornhauer, Benoît Mahault, Johannes Zierenberg
We show that periodically modulating the self-propulsion of active particles in an asymmetric potential can both enhance rectified transport and reverse its direction, even when th…
Density-protected states in active matter under virtual confinement
Giuseppe Fava, Francesco Ginelli, Benoît Mahault
We investigate photo-responsive structure formation in a minimal model of dry active nematics. Combining microscopic simulations with the analysis of the corresponding hydrodynamic…
Breakdown of Emergent Chiral Order and Defect Chaos in Nonreciprocal Flocks
Charlotte Myin, Suropriya Saha, Benoît Mahault
We show that chiral order in two-dimensional nonreciprocal flocking mixtures is generically unstable. Combining large-scale agent-based simulations with a coarse-grained continuum…
Nonequilibrium energetics of sensing and actuation by a smart active particle
Luca Cocconi, Benoît Mahault, Lorenzo Piro
Smart active agents must allocate finite energetic resources across distinct functions, yet the underlying thermodynamic trade-offs remain poorly understood. Here, we introduce a m…
Non-reciprocal interactions between condensates in chemically active mixtures
Jacopo Romano, Martin Kjøllesdal Johnsrud, Benoît Mahault +1
We study the behaviour of catalytically active droplets in multi-component conserved mixtures affected by noise. Working in the thin interface limit, we analytically determine the…
Nonreciprocity as a Generic Mechanism for Demixing in Flocking Mixtures
Charlotte Myin, Benoît Mahault
We show that even weak nonreciprocal alignment leads to large-scale structure formation in flocking mixtures. By combining numerical simulations of a binary Vicsek model and the an…
