Quantum Geometry on Quantum Spacetime: Distance, Area and Volume Operators
Dorothea Bahns, Sergio Doplicher, Klaus Fredenhagen +1
We develop the first steps towards an analysis of geometry on the quantum spacetime proposed in [1]. The homogeneous elements of the universal differential algebra are naturally id…
Perturbative Algebraic Quantum Field Theory and the Renormalization Groups
Romeo Brunetti, Michael Duetsch, Klaus Fredenhagen
A new formalism for the perturbative construction of algebraic quantum field theory is developed. The formalism allows the treatment of low dimensional theories and of non-polynomi…
The generally covariant locality principle -- A new paradigm for local quantum physics
Romeo Brunetti, Klaus Fredenhagen, Rainer Verch
A new approach to the model-independent description of quantum field theories will be introduced in the present work. The main feature of this new approach is to incorporate in a l…
Interacting Quantum Fields on a Curved Background
Romeo Brunetti, Klaus Fredenhagen
A renormalized perturbative expansion of interacting quantum fields on a globally hyperbolic spacetime is performed by adapting the Bogoliubov Epstein Glaser method to a curved bac…
