In two dimensions, particles can have spin and statistics that are different from what we see in three dimensions. These special particles, called anyons, can have any kind of spin and statistics. They are not real particles in our world, but they can be found in certain materials that act like they are in two dimensions. Anyons have been observed in systems showing the fractional quantum Hall effect, where they have fractional charge, spin, and statistics. They may also be important in understanding high temperature superconductivity, although more research is needed to confirm this.
