Quantum fluid

Quantum fluid is a term used to describe fluids that exhibit quantum mechanical effects on a macroscopic scale. These fluids demonstrate properties that cannot be explained by classical fluid mechanics and are often studied in the context of low-temperature physics. Two well-known examples of quantum fluids are: 1. **Superfluid Helium**: At temperatures close to absolute zero, helium-4 and helium-3 can transition into a superfluid state.
