superfluid Definition
- 1a state of matter in which a fluid has zero viscosity and zero entropy, allowing it to flow without any resistance or loss of kinetic energy
- 2a fluid that exhibits this state
Using superfluid: Examples
Take a moment to familiarize yourself with how "superfluid" can be used in various situations through the following examples!
Example
Helium-4 is a superfluid at temperatures below 2.17 K.
Example
Superfluidity was first observed in liquid helium in 1937.
Example
Superfluids can flow through extremely narrow spaces without any friction.

Phrases with superfluid
Bose-Einstein condensate
a state of matter in which a group of bosons (particles with integer spin) collapse into the same quantum state, resulting in a superfluid with unique properties
Example
The Bose-Einstein condensate is a superfluid that behaves like a single entity.
a topological defect that appears in a superfluid when it is rotated, causing the fluid to form a vortex around an axis of rotation
Example
The quantum vortex is a phenomenon that occurs in superfluids when they are rotated.
Andreev reflection
a process in which a quasiparticle in a superfluid reflects off a boundary and becomes a different type of quasiparticle, resulting in a change in its properties
Example
Andreev reflection is a phenomenon that occurs in superfluids when quasiparticles reflect off a boundary.
Summary: superfluid in Brief
The term 'superfluid' [ˈsuːpəfluːɪd] refers to a state of matter in which a fluid has zero viscosity and zero entropy, allowing it to flow without any resistance or loss of kinetic energy. This state is exhibited by fluids such as liquid helium at very low temperatures. Superfluids can flow through extremely narrow spaces without any friction, and exhibit phenomena like Bose-Einstein condensates, quantum vortices, and Andreev reflection.
