Simple patterns, such as stripes, can be created from instabilities that involve linear momentum states of waves. The group of Professor Rolf Binder recently asked the question whether similar instabilities and patterns involving orbital angular (instead of linear) momentum states are possible. They performed theoretical investigations of polaritonic quantum fluids. Details about their findings are in Phys. Rev. Lett. 119, 113903 (2017).
