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…
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…
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…
Enhanced stability and chaotic condensates in multi-species non-reciprocal mixtures
Laya Parkavousi, Navdeep Rana, Ramin Golestanian +1
Random non-reciprocal interactions between a large number of conserved densities are shown to enhance the stability of the system towards pattern formation. The enhanced stability…
Emergent polar order in non-polar mixtures with non-reciprocal interactions
Giulia Pisegna, Suropriya Saha, Ramin Golestanian
Phenomenological rules that govern the collective behaviour of complex physical systems are powerful tools because they can make concrete predictions about their universality class…
