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…
