Nonreciprocal surface tension: anisotropy-induced defect motility and organization
Laya Parkavousi, Suropriya Saha
We show that interfacial nonreciprocity transforms defect dynamics in conserved scalar fields within the framework of the Nonreciprocal Cahn-Hilliard model. Nonreciprocal surface t…
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…
Spinning mixtures: nonreciprocity transfers chirality across scales in scalar densities
Giulia Pisegna, Suropriya Saha
Mixtures of chiral active particles provide a minimal setting where nonreciprocity and chirality intertwine to shape collective dynamics. Here we show that nonreciprocal interactio…
Memory as activity: pattern formation in a conserved scalar field
Vaishnavi Gajendragad, Suropriya Saha
We explore the concept of memory in scalar active matter, focusing on the collective dynamics of particles whose interactions depend on their evolutionary history rather than solel…
Compositional disorder in a multicomponent non-reciprocal mixture: stability and patterns
Laya Parkavousi, Suropriya Saha
The mean compositions of individual components can be tuned to control phase behavior in number-conserving passive mixtures. In this work, we investigate the role of variable avera…
Non-reciprocal mixtures in suspension: the role of hydrodynamic interactions
Giulia Pisegna, Navdeep Rana, Ramin Golestanian +1
The collective chasing dynamics of non-reciprocally coupled densities leads to stable travelling waves which can be mapped to a model for emergent flocking. In this work, we couple…
