Partial vision leads to an unexpected emergent collective behavior in active aligning particles

Raúl Molina-Prados Lallena, José Martín-Roca, Chantal Valeriani

The paper extends the Vicsek model by giving particles limited, directional vision cones, showing how anisotropic and non‑reciprocal perception changes collective motion, leading t…
