Abstract
The study of spectral statistics is of importance in theoretical physics due to its universality and utility as a robust diagnosis of quantum chaos. In this talk, I will firstly present an exact univer-sal scaling form of the spectral form factor for a many-body quantum chaotic (MBQC) system, deriving the “bump-ramp-plateau” behaviour. Secondly, I will provide evidence that the non-Hermitian Ginibre ensemble behaviours emerge in MBQC systems with large system sizes, just as Hermitian Gaussian ensemble behaviours emerge in MBQC systems in late time.
