Active wave-particle clusters Rahil N. Valani and David M. Paganin University of Oxford, Department of Physics Published 8 December 2025 Active clusters of self-propelled particles can display rich collective dynamics when their interactions are mediated by waves. In our recent work with the brilliant and kind-hearted physicist David Paganin, we numerically investigated clusters of walking and superwalking droplets - a hydrodynamic system in which each droplet is coupled to the surface waves it
