Instability thresholds for de Sitter and Minkowski spacetimes in holographic semiclassical gravity
Akihiro Ishibashi, Kengo Maeda, Takashi Okamura
We study the stability of -dimensional () de Sitter and Minkowski spacetimes within the framework of semiclassical gravity sourced by a strongly coupled quantum field w…

The higher dimensional instabilities of AdS in holographic semiclassical gravity
Akihiro Ishibashi, Kengo Maeda, Takashi Okamura
In the framework of AdS/CFT duality, we consider the semiclassical problem in general quadratic theory of gravity. We construct asymptotically global AdS and hyperbolic~(topologica…
