Hartree方程相干态的半经典传播

Semiclassical Propagation of Coherent States for the Hartree equation

Agissilaos Athanassoulis, Thierry Paul, Federica Pezzotti, Mario Pulvirenti

摘要:

本文研究了具有一个给定外势的初始相干态的非线性Hartree方程。在适当的光滑性假设下,我们用一个依赖于时间的相干态来近似解,相干态的相位和振幅可以由经典流来确定。在$L^2$中,误差可以通过$C \sqrt {\var}$估计,$\var$是普朗克常量。最后,我们提出了一个完整的形式渐近展开。

英文摘要:

In this paper we consider the nonlinear Hartree equation in presence of a given external potential, for an initial coherent state. Under suitable smoothness assumptions, we approximate the solution in terms of a time dependent coherent state, whose phase and amplitude can be determined by a classical flow. The error can be estimated in $L^2$ by $C \sqrt {\var}$, $\var$ being the Planck constant. Finally we present a full formal asymptotic expansion.
