Thermal field theory correlators in the large- limit and the spectral duality relation
Sašo Grozdanov, Mile Vrbica
In Ref.~\cite{Grozdanov:2024wgo}, we derived a spectral duality relation applicable to the spectra of 3 conformal field theories (CFTs) and their holographically dual 4 black…
Bouncing geodesics, black hole singularities, and singularities of thermal correlators
Sašo Grozdanov, Samuel Valach, Mile Vrbica
Bouncing geodesics have been used as valuable probes of black hole singularities. In the dual boundary theory, the presence of bouncing geodesics is encoded in the analytic structu…
The algebraic structure of the gradient expansion in linearised classical hydrodynamics
Sašo Grozdanov, Mile Vrbica
In this work, we systematically treat the ambiguities that generically arise in the gradient expansion of any hydrodynamic theory. While these ambiguities do not affect the physica…
Duality and four-dimensional black holes: gravitational waves, algebraically special solutions, pole skipping, and the spectral duality relation in holographic thermal CFTs
Sašo Grozdanov, Mile Vrbica
The physics of gravitational waves and other classical fields on specifically four-dimensional backgrounds of black holes exhibits electric-magnetic-like dualities. In this paper,…
Duality Constraints on Thermal Spectra of 3d Conformal Field Theories and 4d Quasinormal Modes
Sašo Grozdanov, Mile Vrbica
Thermal spectra of correlation functions in holographic 3d large-N conformal field theories (CFTs) correspond to quasinormal modes of classical gravity and other fields in asymptot…
Pole-skipping of gravitational waves in the backgrounds of four-dimensional massive black holes
Sašo Grozdanov, Mile Vrbica
Pole-skipping is a property of gravitational waves dictated by their behaviour at horizons of black holes. It stems from the inability to unambiguously impose ingoing boundary cond…
