Spectral form factors for curved spacetimes with horizon
САЖЕТАК:
In this talk, we present 2412.19672 “Spectral form factors for curved spacetimes with horizon”. In a recent series of papers (e.g. 2208.14744, 2301.11780 and 2312.14109), it was noted that the spectral form factor
defined for normal modes on the BTZ black hole background with a stretched horizon exhibits the dip ramp-plateau structure in the massless scalar case. Normal modes are understood as the scalar field modes on the curved background with a Dirichlet boundary condition imposed at the horizon instead of the usual infalling boundary condition for quasi-normal modes. In this paper, we have extended the analysis by considering massive scalar on the BTZ background, the de Sitter case as well as the generalized (complex-valued) two- and three-level form factor.
