摘要:Water waves can span scales of hundreds of kilometers to a few millimeters with fascinating and complex behaviors. At small scales, when gravity and surface tension are equally important, water waves exhibit a large variety of phenomena, one of which is the quantum-like behaviors when droplets walk on the surface of a vibrating bath, and almost all the classic quantum experiments, such as single and double slit experiments, tunneling and locking orbits, can be realized in the Faraday-bouncing droplet system. At large scales, a large-amplitude internal solitary wave can excite a fully localized ‘rip’ region on the sea surface, which is called the ‘surface signature’or ‘tide rip’in the literature. This phenomenon is very much like Bohr’s model of the hydrogen atom in the semi-classical limit in quantum mechanics. We describe the reasons for these similarities based on the combination of modeling, numerical simulation and multi-scale analysis.
