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.
Quantum field theory and Hopf algebra cohomology
Christian Brouder, Bertfried Fauser, Alessandra Frabetti +1
We exhibit a Hopf superalgebra structure of the algebra of field operators of quantum field theory (QFT) with the normal product. Based on this we construct the operator product an…
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…
Three-dimensional Quantum Supergravity and Supersymmetric Spin Foam Models
Etera R. Livine, Robert Oeckl
We show how super BF theory in any dimension can be quantized as a spin foam model, generalizing the situation for ordinary BF theory. This is a first step toward quantizing superg…
A "general boundary" formulation for quantum mechanics and quantum gravity
Robert Oeckl
I propose to formalize quantum theories as topological quantum field theories in a generalized sense, associating state spaces with boundaries of arbitrary (and possibly finite) re…
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…
