Implication

Experiments reveal self-sustained frictional cooling in active particles, suggesting new avenues for controlling swarm robotics.

Key Points

  • Self-sustained frictional cooling enables particles to reach extremely low temperatures without external contact.
  • Experiments and simulations demonstrate how active particles lose heat via dry friction in dense environments.
  • This cooling phenomenon opens up possibilities for enhancing swarm robotics with tunable mechanisms based on friction.
  • The interplay between activity and dry friction can regulate the dynamical and structural properties of swarms.
