| Outline of Final Research Achievements |
When a fluid layer with a free surface is subjected to vertical oscillation, Faraday waves can be observed. Due to their dynamic and nonlinear properties, Faraday waves exhibit complex patterns, such as spatiotemporal chaos. This has posed interesting challenges for many years. In this project, we aim to exploit Faraday waves as information-processing substrates based on the framework of reservoir computing. In particular, we show that they can be used to design timers (or timing control), which require a certain amount of memory to recognize time duration. We also aim to characterize the memory capacity of Faraday waves.
