Hydrodynamic radioactivity analog

A prove-of-concept quantum analog of radioactive processes using a macroscopic hydrodynamic system was demonstrated. The experimental set up contains a liquid container compressing three regions with different depths. Due to controlled mechanical vibrations in the 150 to 180 Hz frequency range, walker droplets are continuously produced. The described experimental set up corresponds to a hydrodynamic analog of a radioactive sample with a constant averaged activity. The walker droplets were videotaped, and a droplet tracking program was developed for tracing the trajectories of the particles. Interestingly, the droplets form from the crests of the waves in the deepest region of the liquid container, then interact with their waves, and walk in a straight path until they tunnel through a hydrodynamic analog of a quantum barrier region.
