Convergence of the quantum Navier–Stokes–Poisson equations to the incompressible Euler equations for general initial data.

In this paper, we are concerned with the rigorous proof of the convergence of the quantum Navier–Stokes-Poisson system to the incompressible Euler equations via the combined quasi-neutral, vanishing damping coefficient and inviscid limits in the three-dimensional torus for general initial data. Furthermore, the convergence rates are obtained. [ABSTRACT FROM AUTHOR]
