非定域四次Gross-Pitaevskii方程的基态解

Ground states for a nonlocal cubic-quartic Gross-Pitaevskii equation

Yongming Luo, Athanasios Stylianou

摘要:

证明了一类广义非局部3 - 4阶Gross-Pitaevskii方程基态解的存在性和定性性质。利用球面上的山路论证和构造适当局部化的Palais-Smale序列,我们能够证明实正基态作为鞍点的存在性.分析部署在可能的状态的集合中,从而克服了能量在下面是无界的问题。我们还证明了相应的非本地Pohozaev身份没有休息项,分析的一个重要组成部分。

英文摘要:

We prove existence and qualitative properties of ground state solutions to a generalized nonlocal 3rd-4th order Gross-Pitaevskii equation. Using a mountain pass argument on spheres and constructing appropriately localized Palais-Smale sequences we are able to prove existence of real positive ground states as saddle points. The analysis is deployed in the set of possible states, thus overcoming the problem that the energy is unbounded below. We also prove a corresponding nonlocal Pohozaev identity with no rest term, a crucial part of the analysis.
