Two-fluid hydrodynamic description of ordered systems
Two-fluid hydrodynamic description of ordered systems is a scholarly work, published in 1974 in ''Reviews of Modern Physics''. The main subjects of the publication include classical mechanics, high temperature superconductor, physics, superfluidity, conservation law, phase change, superconductivity, ultracold atom, symmetry, equation of state, equations of motion, momentum, phase, superfluid helium-4, and condensed matter physics. A unified description of systems with a condensed phase in terms of hydrodynamic equations of motion is given.
