About
The Vicsek model (1995) is the minimal flocking model: each particle moves at fixed speed, aligning its direction with neighbors within radius r, plus noise η. Despite simplicity, it shows a genuine phase transition from disorder to ordered collective motion — an active matter universality class distinct from equilibrium systems.
