The operator product expansion converges in massless -theory
Jan Holland, Stefan Hollands, Christoph Kopper
It has been shown recently that the mathematical status of the operator product expansion (OPE) is better than was expected before: namely considering massive Euclidean -theor…
Casimir energies in spherically symmetric background potentials revisited
Matthew Beauregard, Michael Bordag, Klaus Kirsten
In this paper we reconsider the formulation for the computation of the Casimir energy in spherically symmetric background potentials. Compared to the previous analysis, the technic…
The Weyl tensor correlator in cosmological spacetimes
Markus B. Fröb
We give a general expression for the Weyl tensor two-point function in a general Friedmann-Lemaître-Robertson-Walker spacetime. We work in reduced phase space for the perturbations…
Instabilities of extremal rotating black holes in higher dimensions
Stefan Hollands, Akihiro Ishibashi
Recently, Durkee and Reall have conjectured a criterion for linear instability of rotating, extremal, asymptotically Minkowskian black holes in dimensions, such as the Mye…
generalized Robin boundary conditions and quantum vacuum fluctuations
J. M. Munoz-Castaneda, J. Mateos Guilarte
The effects induced by the quantum vacuum fluctuations of one massless real scalar field on a configuration of two partially transparent plates are investigated. The physical prope…
Mapping AdS to dS spaces and back
Adriana Di Dato, Markus B. Fröb
We derive a map between Einstein spaces of positive and negative curvature, including scalar matter. Starting from a space of positive curvature with some dimensions compactified o…
