Wave-mediated interactions can drive rich collective dynamics in active particle clusters. We study walking droplet clusters that form stable bound states with collective excitation modes and show similarities with nuclear physics.

Our work on quantization in models of a walking droplet in a harmonic potential is now published. We show that the system reduces to a perturbed simple harmonic oscillator that gives rise to a quantum-like discrete energy spectrum as opposed to a continuous energy spectrum.

Megastable quantization in generalized pilot-wave hydrodynamics
A classical particle in a harmonic potential gives rise to a continuous energy spectra, whereas the corresponding quantum particle exhibits countably infinite quantized energy levels. In recent years,...
