Non-perturbative, background independent canonical quantum gravity in Fock representations
Thomas Thiemann
It is commonly believed that a quantum field theory of General Relativity requires a non-perturbative formulation. In addition, the background independence of classical General Rel…
Non-perturbative, background independent Fock representations for canonical quantum gravity
T. Thiemann
A UV complete quantum field theory of general relativity is believed to require a non-perturbative approach. Moreover, background independence of classical general relativity suppl…
Quantum Field Theory of Black Hole Perturbations with Backreaction VI. Apparent Horizons, Quasi-Local Mass and Effective Classical Metrics
Jonas Neuser, Thomas Thiemann
In a recent series of papers we developed a first-principle and gauge invariant approach to black hole perturbation theory valid to any order. We included back reaction effects to…
(Quantum) reference frames, relational observables, gauge reduction and physical interpretation
Thomas Thiemann
It is mandatory to know how to operationally define and translate a reference frame into mathematics, in order that a physical interpretation of theory calculations in terms of obs…
Quantum Field Theory of Black Hole Perturbations with Backreaction V. Beyond Second Order Perturbations
Jonas Neuser, Thomas Thiemann
Black hole perturbation theory beyond second order is not well understood because typically one defines the meaning of gauge invariance order by order which is ambiguous. In this s…
Asymptotically safe canonical quantum gravity: Gaussian dust matter
Renata Ferrero, Thomas Thiemann
In a recent series of publications we have started to investigate possible points of contact between the canonical (CQG) and the asymptotically safe (ASQG) approach to quantum grav…
