Collective behavior in life and quantum physics

Individuals usually lead fairly solitary lives; except on the occasions when they congregate for social activities, like, baseball or football. On these occasions they demonstrate a type of collective behavior which is motivated by their interests.
Do you know that we can find the same phenomenon in quantum physics? Distinguishable noninteracting particles work separately. However after interacting with another distinguishable particle, they often work together and demonstrate collective behavior. We call these phenomena composite particles. Do you know any of the well-known composite particles in physics? Ubiquitous examples include anyons, and cobosons. But there are a plethora of other examples which inspire a rapidly developing field of research.
