Non-perturbative Quantum Gravity in Fock representations
Thomas Thiemann
Perturbative quantum gravity starts from prescribing a background metric. That background metric is then used in order to carry out two separate steps: 1. One splits the non-pertur…
Quantum Field Theory of Black Hole Perturbations with Backreaction III. Spherically symmetric 2nd order Maxwell sector
Jonas Neuser, Thomas Thiemann
In this paper we extend reduced phase space approach to black hole perturbation theory to Maxwell matter. We expand the resulting reduced Hamiltonian to second order in the gravito…
Quantum Field Theory of Black Hole Perturbations with Backreaction II. Spherically symmetric 2nd order Einstein sector
Jonas Neuser, Thomas Thiemann
In this second paper of our series we focus on the classical pure gravity sector of spherically symmetric black hole perturbations and expand the reduced Hamiltonian to second orde…
Quantum Field Theory of Black Hole Perturbations with Backreaction: I. General framework
Thomas Thiemann
In a seminal work, Hawking showed that natural states for free quantum matter fields on classical spacetimes that solve the spherically symmetric vacuum Einstein equations are KMS…
Symmetry reduction, gauge reduction, backreaction and consistent higher order perturbation theory
Thomas Thiemann
For interacting classical field theories such as general relativity exact solutions typically can only be found by imposing physically motivated (Killing) {\it symmetry} assumption…
Asymptotically safe -- canonical quantum gravity junction
Thomas Thiemann
The canonical (CQG) and asymptotically safe (ASQG) approach to quantum gravity share to be both non-perturbative programmes. However, apart from that they seem to differ in several…
Relational Lorentzian Asymptotically Safe Quantum Gravity: Showcase model
Renata Ferrero, Thomas Thiemann
In a recent contribution we identified possible points of contact between the asymptotically safe and canonical approach to quantum gravity. The idea is to start from the reduced p…
