Active Matter: MIPS & Flocking

Controls

Particles N: 200 Self-propulsion v₀: 2.0 Rotational noise Dr: 0.20 Alignment η: 0.3 Repulsion radius r: 15 Reset Particles

Active Brownian Particles self-propel at speed v₀ with angular noise Dr. MIPS occurs at high density + low noise: slow particles accumulate into dense clusters that trap fast neighbors. Alignment (Vicsek-like) promotes flocking. Emergent collective behavior arises from purely local interactions.
