We perform a rigorous analysis of the anelastic approximation for the Gross-Pitaevskii equation with $x$-dependent chemical potential. For general initial data and periodic boundary condition, we show that as $\eps\to 0$, equivalently the Planck constant tends to zero, the density $|\psi^{\eps}|^{2}$ converges toward the chemical potential $\rho_{0}(x)$ and the velocity field converges to the anelastic system. When the chemical potential is a constant, the anelastic system will reduce to the…

Asymptotic limit of the Gross-Pitaevskii equation with general initial data
This paper mainly concerns the mathematical justification of the asymptotic limit of the Gross-Pitaevskii equation with general initial data in the natural energy space over the whole space. We give


Semiclassical Limit of the Gross-Pitaevskii Equation in an Exterior Domain
In this paper, we study the semiclassical limit of the Gross-Pitaevskii equation (a cubic nonlinear Schrödinger equation) with the Neumann boundary condition in an exterior domain. We prove that
Anelastic Limits for Euler Type Systems
In this paper, we present rigorous derivations of anelastic limits for compressible Euler type systems when the Mach (or Froude) number tends to zero. The first and main part is to prove local
Anelastic Approximation as a Singular Limit of the Compressible Navier–Stokes System
Considering compressible Navier–Stokes system in a slab geometry in the regime when both Mach and Froude numbers vanish at the same rate, we study the behavior of corresponding weak solutions, that
convergence of the vlasov-poisson system to the incompressible euler equations
We consider the displacement of an electronic cloud generated by the local difference of charge with a uniform neutralizing background of non-moving ions. The equations are given by the
This paper is devoted to the proof of the convergence of the Vlasov-Poisson system to the incompressible Euler equations in the so-called quasi-neutral regime for cold electrons. The convergence is
On Pressureless Gases Driven by a Strong Inhomogeneous Magnetic Field
The asymptotic behavior of the solutions to a system governing the motion of a pressureless gas that is submitted to a strong, inhomogeneous magnetic field of variable amplitude but fixed direction leads to a multidimensional Burgers-type system on the velocity field.
Hydrodynamic limits of the nonlinear Klein–Gordon equation
We perform the mathematical derivation of the compressible and incompressible Euler equations from the modulated nonlinear Klein–Gordon equation. Before the formation of singularities in the limit
Averaging theorems for conservative systems and the weakly compressible Euler equations
Abstract A generic averaging theorem is proven for systems of ODEs with two-time scales that cannot be globally transformed into the usual action-angle variable normal form for such systems. This
Quasineutral Limit of the Schrodinger-Poisson System in Coulomb Gauge
The zero Debye length asymptotic of the Schrodinger- Poisson system in Coulomb gauge for ill-prepared initial data is stud- ied. We prove that when the scaled Debye length λ → 0, the current density
An example of low Mach (Froude) number effects for compressible flows with nonconstant density (height) limit
The purpose of this work is to study an example of low Mach (Froude) number limit of compressible flows when the initial density (height) is almost equal to a function depending on x . This allows us
