Query: Influence of quantum energy equation on electronic plasma oscillations   Five-moment approximation in hydrodynamics includes not only continuity
equation and momentum balance equation, but also energy equation. Set of
hydrodynamic equations is presented for system of non-relativistic quantum
particles with Coulomb interaction. This set of equations is linearized, and
dispersion relation for Langmuir waves in quasi-neutral system of electrons and
immobile ions is obtained.
