In 2005, Yves Couder and Emmanuel Fort discovered that droplets walking on a vibrating fluid bath exhibit features previously thought to be peculiar to the quantum realm. Since 2010, this hydrodynamic system has been the focus of John Bush’s Hydrodynamic Quantum Analogs (HQA) research group. Particular attention has been given to identifying new hydrodynamic quantum analogs in the laboratory, and to rationalizing the emergent quantum-like behaviour theoretically. The group also developed and explored theoretically a broader class of pilot-wave systems that provide a mathematical bridge between the walking-droplet system and the dynamics proposed by Louis de Broglie and others for the microscopic, quantum realm. For an overview, it is suggested reading the reviews on the subject, especially the most recent one, Hydrodynamic Quantum Analogs, as appeared in 2020 in Reviews of Progress in Physics.
