Walking drops on Faraday waves are one of the rare examples of non-quantum wave-particle duality. A series of striking experiments with one walking drop has led to behaviors that were thought to be the peculiar to the quantum scale. I will present a recent numerical and experimental investigation involving the coupling of two walking drops. To our great surprise, we found that the statistical behavior of this system shares some non-expected features of collective emission of photons in quantum optics, including superradiance and violation of Bell's inequality.

Short bio: Matthieu Labousse is a theoretical physicist and works at ESPCI Paris -PSL as a CNRS researcher. His research is carried out in the laboratory Gulliver. He combines numerical, theoretical and even sometimes experimental approaches to investigate the physics of self-organization in complex systems including: programmable active matter, metamaterials, design of polymer systems, Waves and memory.
