摘要
李等人(Phys Rev Lett 127(17):170602, 2021)最近针对吉尼布雷集合提出的耗散谱形式因子(DSFF)是研究耗散量子系统普遍特性的关键工具。在这项工作中,我们计算了一大类具有实数或复数条目的随机矩阵的 DSFF,直至中间时间尺度,证实了 Li 等人的预测(Phys Rev Lett 127(17):170602, 2021)。实数情况下 DSFF 的解析公式以前是未知的。此外,我们还证明,在短时间内,DSFF 的连通分量表现出一种非普遍的修正,这取决于条目的第四积。这些结果基于 Cipolloni 等人(Electron J Prob 26:1-61, 2021)和 Cipolloni 等人(Commun Pure Appl Math 76(5):946-1034, 2023).
The Dissipative Spectral Form Factor for I.I.D. Matrices
The dissipative spectral form factor (DSFF), recently introduced in Li et al. (Phys Rev Lett 127(17):170602, 2021) for the Ginibre ensemble, is a key tool to study universal properties of dissipative quantum systems. In this work we compute the DSFF for a large class of random matrices with real or complex entries up to an intermediate time scale, confirming the predictions from Li et al. (Phys Rev Lett 127(17):170602, 2021). The analytic formula for the DSFF in the real case was previously unknown. Furthermore, we show that for short times the connected component of the DSFF exhibits a non-universal correction depending on the fourth cumulant of the entries. These results are based on the central limit theorem for linear eigenvalue statistics of non-Hermitian random matrices Cipolloni et al. (Electron J Prob 26:1–61, 2021) and Cipolloni et al. (Commun Pure Appl Math 76(5): 946–1034, 2023).
