自由费米子的普适性及半经典薛定谔算子的局部 Weyl 律

Universality for free fermions and the local Weyl law for semiclassical Schrödinger operators

Alix Deleporte, Gaultier Lambert

AI总结:

本文研究了半经典极限下薛定谔算子谱投影算子的局部渐近性,证明了其重标度积分核向普适模型的收敛,并由此推导出自由费米子点过程在微观、宏观和介观尺度的涨落普适性及中心极限定理。

摘要:

我们研究在半经典极限 $\hbar\to0$ 下,与 $\mathbb{R}^n$ 上的薛定谔算子 $-\hbar^2Δ+V$ 相关的谱投影算子的局部渐近性。我们证明了该投影算子重标度积分核在经典允许区域及其边界上向一个普适模型的局部一致收敛。这蕴含了相应自由费米子(行列式)点过程在体相和正则边界点周围的微观涨落普适性。我们的结果适用于任意维度 $n\ge 1$ 下的一大类光滑势。这些结果还通过研究点过程的宏观和介观涨落得到了补充。我们得到了宏观线性统计的尾界,并且在 $n\geq 2$ 条件下,得到了体相中宏观和介观线性统计的中心极限定理。

英文摘要:

We study local asymptotics for the spectral projector associated to a Schrödinger operator $-\hbar^2Δ+V$ on $\mathbb{R}^n$ in the semiclassical limit as $\hbar\to0$. We prove local uniform convergence of the rescaled integral kernel of this projector towards a universal model, inside the classically allowed region as well as on its boundary. This implies universality of microscopic fluctuations for the corresponding free fermions (determinantal) point processes, both in the bulk and around regular boundary points. Our results apply for a general class of smooth potentials in arbitrary dimension $n\ge 1$. These results are complemented by studying both macroscopic and mesoscopic fluctuations of the point process. We obtain tail bounds for macroscopic linear statistics and, provided $n\geq 2$, a central limit theorem for both macroscopic and mesoscopic linear statistics in the bulk.
