Research Abstract

Collective motion is one of the hot topic in an interdisciplinary research field. Collection of camphor boats exhibits spacio-temporal pattern on a ring-shaped water channel. To clarify the mechanism in detail, we measured the basic parameters such as supply and sublimation rate of camphor molecules. Based on our measurement, we estimated the relaxation distance of camphor surface concentration behind the boat. This distance tells us the interaction between the boats. Next, we observed collective behavior of camphor disks on circular water surface, in order to discover novel collective motion. As the result, we successfully found intermittent motion of camphor disks with high number density. This behavior is novel collective motion induced by interaction between the disks.
