The general boundary approach to quantum gravity
Robert Oeckl
We present an approach to quantum gravity based on the general boundary formulation of quantum mechanics, path integral quantization, spin foam models and renormalization.
Minkowski vacuum in background independent quantum gravity
Florian Conrady, Luisa Doplicher, Robert Oeckl +2
We consider a local formalism in quantum field theory, in which no reference is made to infinitely extended spacial surfaces, infinite past or infinite future. This can be obtained…
Schroedinger's cat and the clock: Lessons for quantum gravity
Robert Oeckl
I review basic principles of the quantum mechanical measurement process in view of their implications for a quantum theory of general relativity. It turns out that a clock as an ex…
Renormalization of Discrete Models without Background
Robert Oeckl
Conventional renormalization methods in statistical physics and lattice quantum field theory assume a flat metric background. We outline here a generalization of such methods to mo…
