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…

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…

Boson stars with nonlinear sigma models
Pablo A. Cano, Ludovico Machet, Charlotte Myin
Boson stars arise as solutions of a massive complex scalar field coupled to gravity. A variety of scalar potentials, giving rise to different types of boson stars, have been studie…
