高温下矩阵系综的Poisson统计

Poisson statistics for matrix ensembles at large temperature

Florent Benaych-Georges, Sandrine Péché

摘要:

在这篇文章中,我们考虑$β$ -系综,即具有联合分布$$\frac{1}{Z_N(β)}|Δ(λ)|^βe^{- \frac{Nβ}{4}\sum_{i=1}^Nλ_i^2}d λ,$$的实数线上的随机位置的粒子的集合,其中$β\to 0$为$N\to\infty$。我们简要介绍了全球政权,然后考虑当地政权。在$Nβ$有界的情况下,证明了局部特征值统计量在任意实数附近渐近于Poisson点过程的局部特征值统计量.在$Nβ\to\infty$的情况下,我们证明了在这个方向上的部分结果。

英文摘要:

In this article, we consider $β$-ensembles, i.e. collections of particles with random positions on the real line having joint distribution $$\frac{1}{Z_N(β)}|Δ(λ)|^βe^{- \frac{Nβ}{4}\sum_{i=1}^Nλ_i^2}d λ,$$ in the regime where $β\to 0$ as $N\to\infty$. We briefly describe the global regime and then consider the local regime. In the case where $Nβ$ stays bounded, we prove that the local eigenvalue statistics, in the vicinity of any real number, are asymptotically to those of a Poisson point process. In the case where $Nβ\to\infty$, we prove a partial result in this direction.
