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…
