薛定谔-牛顿模型的定态解--一种ODE方法

Stationary solutions of the Schrödinger-Newton model - An ODE approach

Philippe Choquard, Joachim Stubbe, Marc Vuffray

摘要:

证明了任意空间维数$d$中Schrödinger-Newton模型平稳球对称正解的存在唯一性.我们的结果是基于相应的二阶微分方程系统的分析。结果表明,$d=6$是有限能量解存在的关键,正球对称解的方程对所有$d\geq 6$都退化为Lane-Emden方程.我们的结果特别暗示了二维自引力粒子的定态解的存在性,并缩小了$d=1$和$d=3$中变分证明之间的差距。

英文摘要:

We prove the existence and uniqueness of stationary spherically symmetric positive solutions for the Schrödinger-Newton model in any space dimension $d$. Our result is based on an analysis of the corresponding system of second order differential equations. It turns out that $d=6$ is critical for the existence of finite energy solutions and the equations for positive spherically symmetric solutions reduce to a Lane-Emden equation for all $d\geq 6$. Our result implies in particular the existence of stationary solutions for two-dimensional self-gravitating particles and closes the gap between the variational proofs in $d=1$ and $d=3$.
