Hidden Symmetry of Kerr-deSitter from Manifest Symmetry of Painlevé VI

Stefan Hollands, Akihiro Ishibashi, Jochen Zahn

We show that the recently discovered ``mass symmetries" of the radial Teukolsky equation for Kerr-deSitter black holes can be understood from a corresponding symmetry of the Painle…

Quantum fields on self-similar spacetimes

Jochen Zahn

We study scalar (not necessarily conformal) quantum fields on self-similar spacetimes. It is shown that in states respecting the self-similarity the expectation value of the stress…

The Weyl anomaly in interacting quantum field theory on curved spacetimes

Markus B. Fröb, Jochen Zahn

We define the notion of Weyl anomalies, measuring the violation of local scale invariance, in interacting quantum field theory on curved spacetimes in the framework of locally cova…

Quantum effects in near-extremal charged black hole spacetimes

Maria Alberti, Jochen Zahn

We compute the semiclassical current and stress-energy fluxes both at the event and Cauchy horizon of a near-extremal Reissner-Nordström black hole. We consider a minimally-coupled…

Long-range correlations of the stress tensor near the Cauchy horizon

Christiane Klein, Jochen Zahn

We show that the stress tensor of a real scalar quantum field on Reissner-Nordstr{ö}m-de Sitter spacetime exhibits correlations over macroscopic distances near the Cauchy horizon.…

Quantum Instability of the Cauchy Horizon in Reissner-Nordström-deSitter Spacetime

Stefan Hollands, Robert M. Wald, Jochen Zahn

In classical General Relativity, the values of fields on spacetime are uniquely determined by their values at an initial time within the domain of dependence of this initial data s…
