圆幺正系综的功率谱

Power spectrum of the circular unitary ensemble

Roman Riser, Eugene Kanzieper

摘要:

我们研究了从圆形酉系综${\rm CUE}(N)$中抽取的随机矩阵的本征角的功率谱,并证明了它可以用Fredholm行列式、Toeplitz行列式或第六Painlevé函数来计算。在无限维矩阵的极限$N\rightarrow\infty$中,我们导出了包含第五个Painlevé超越的功率谱的${\it\, concise\,}$无参数公式,并用${\rm Sine}_2$行列式随机点场来解释它.此外,我们还讨论了预测功率谱定律的普适性,并将其制成表格(参见http://eugenekanzieper.faculty.hit.ac.il/data.html),以便于随机矩阵理论和量子混沌实践者使用。

英文摘要:

We study the power spectrum of eigen-angles of random matrices drawn from the circular unitary ensemble ${\rm CUE}(N)$ and show that it can be evaluated in terms of either a Fredholm determinant, or a Toeplitz determinant, or a sixth Painlevé function. In the limit of infinite-dimensional matrices, $N\rightarrow\infty$, we derive a ${\it\, concise\,}$ parameter-free formula for the power spectrum which involves a fifth Painlevé transcendent and interpret it in terms of the ${\rm Sine}_2$ determinantal random point field. Further, we discuss a universality of the predicted power spectrum law and tabulate it (follow http://eugenekanzieper.faculty.hit.ac.il/data.html) for easy use by random-matrix-theory and quantum chaos practitioners.
