AI总结:

本文研究了具有非谐振子势的聚焦非线性薛定谔方程的吉布斯测度,揭示了一维和高维情况下测度可积性的二元性,并发现亚谐振子势下存在新的临界非线性。

摘要:

在本文中,我们研究了具有非谐振子势的聚焦非线性薛定谔方程的吉布斯测度。我们建立了在一维和高维情况下,径向数据下测度可积性和不可积性的二元性。这扩展了第三、第四作者与Robert和Seong(2022)最近的结果,其中讨论了具有谐振子势的聚焦吉布斯测度。值得注意的是,在亚谐振子势的情况下,我们识别出一个新的临界非线性(低于通常的质量临界指数),使得吉布斯测度表现出相变。主要挑战来自于对具有非谐振子势的薛定谔算子的本征值和本征函数的有限理解。我们通过运用第一、第二作者(2022)最近的工作中的技术来克服这一困难。

英文摘要:

In this paper, we investigate the Gibbs measures associated with the focusing nonlinear Schrödinger equation with an anharmonic potential. We establish a dichotomy for normalizability and non-normalizability of the Gibbs measures in one dimension and higher dimensions with radial data. This extends a recent result of the third and fourth authors with Robert and Seong (2022), where the focusing Gibbs measures with a harmonic potential were addressed. Notably, in the case of a subharmonic potential, we identify a novel critical nonlinearity (below the usual mass-critical exponent) for which the Gibbs measures exhibit a phase transition. The primary challenge emerges from the limited understanding of eigenvalues and eigenfunctions of the Schrödinger operator with an anharmonic potential. We overcome the difficulty by employing techniques related to a recent work of the first two authors (2022).
