Automated excerpt

We have 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. We began by revisiting a number of the early hydrodynamic quantum analogs (HQAs) discovered by Yves Couder, Emmanuel Fort and collaborators in Paris, including walker diffraction, orbital walker dynamics, crystal vibrations and walker tunneling. Doing so has revealed the possibility of capturing additional quantum features with classical pilot-wave systems.
