Exploring quantum fields in rotating black holes
Christiane K. M. Klein
In this paper, we discuss the Unruh state for a free scalar quantum field on Kerr-de Sitter under the assumption of mode stability. We summarise the proof of its Hadamard property…
The Teukolsky scalar as a gateway for quantizing gravity on rotating black holes
Christiane K. M. Klein
The quantization of linearized gravity on black hole spacetimes and the construction of states for that theory is a sought-after, yet difficult achievement. One of the main reasons…
Infinite quantum twisting at the Cauchy horizon of rotating black holes
Christiane Klein, Mojgan Soltani, Marc Casals +1
We present a numerical calculation of the expectation value of the quantum angular-momentum current flux density for a scalar field in the Unruh state near the inner horizon of a K…
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.…
Universality of the quantum energy flux at the inner horizon of asymptotically de Sitter black holes
Peter Hintz, Christiane Klein
Recently, it was found that the energy flux of a free scalar quantum field on a Reissner-Nordström-de Sitter spacetime has a quadratic divergence towards the inner horizon of the b…
