🧬 Nanoparticle Self-Assembly: 2D Lennard-Jones Crystal Growth

Interactive 2D model of nanoparticle self-assembly: Lennard-Jones discs under Langevin dynamics condense from gas into droplets, hexagonal crystals or glass depending on attraction strength versus temperature. Drag discs with the mouse to pull them out of a cluster, anneal the system slowly, or add an attractive substrate and watch contacts, hexagonal order and cluster size evolve live.
