Formation and evaporation of quantum black holes from the decoupling mechanism in quantum gravity
Johanna N. Borissova, Alessia Platania
We propose a new method to account for quantum-gravitational effects in cosmological and black hole spacetimes. At the core of our construction is the "decoupling mechanism": when…
Towards effective actions for the continuum limit of spin foams
Johanna N. Borissova, Bianca Dittrich
Spin foams arise from a quantization of classical gravity expressed via the Plebanski action. Key open questions related to the continuum limit of spin foams are whether general re…
Scale-invariance at the core of quantum black holes
Johanna N. Borissova, Aaron Held, Niayesh Afshordi
We study spherically-symmetric solutions to a modified Einstein-Hilbert action with Renormalization Group scale-dependent couplings, inspired by Weinberg's Asymptotic Safety scenar…
