Boojum (superfluidity)
ID: boojum-superfluidity
Boojum is a term used in the context of superfluidity and condensed matter physics. Specifically, it refers to a type of topological defect known as a "vortex" that can occur in superfluid helium-3 (He-3). The term comes from the analogy of the "Jabberwocky" story by Lewis Carroll, where a Boojum is a particular type of fantastical creature.
