Quantum fluid

-

Quantum Liquid - a name given to quantum physical models describing multi-particle systems of interacting particles. The quantum liquid is analogous to a classical liquid (such as water), in which intermolecular interactions determine the properties of this liquid as opposed to quantum gas models in which the effects are omitted or a correction to the free particle models.

Examples of quantum liquids:

Quantum fluids have strong correlations, which in practice often means that they can not be used in perturbing techniques. Such models deal with highly correlated physics.

This work was covered in 1951 by censorship in Poland, subject to immediate withdrawal from libraries. wiki
