Locally covariant approach to effective quantum gravity
Romeo Brunetti, Klaus Fredenhagen, Kasia Rejzner
Despite the fact that quantum gravity is non-renormalisable, a consistent and mathematically rigorous construction of a perturbation series is possible. This is based on the use of…
The observables of a perturbative algebraic quantum field theory form a factorization algebra
Owen Gwilliam, Kasia Rejzner
We demonstrate that perturbative algebraic QFT methods, as developed by Fredenhagen and Rejzner, naturally yields a factorization algebras of observables for a large class of Loren…
Unitary, anomalous Master Ward Identity and its connections to the Wess-Zumino condition, BV formalism and -algebras
Romeo Brunetti, Michael Dütsch, Klaus Fredenhagen +1
The C*-algebraic construction of QFT by Buchholz and one of us relies on the causal structure of spacetime and a classical Lagrangian. In one of our previous papers we have introdu…
Quantization, dequantization, and distinguished states
Eli Hawkins, Christoph Minz, Kasia Rejzner
Geometric quantization is a natural way to construct quantum models starting from classical data. In this work, we start from a symplectic vector space with an inner product and --…
Chirality in 2d pAQFT
Sam Crawford, Kasia Rejzner, Benoit Vicedo
In this article, which builds upon the work done in our previous paper, the chiral aspects of 2dcft on globally hyperbolic Lorentzian manifolds are developed and explored within th…
An algebraic QFT approach to the Wetterich equation on Lorentzian manifolds
Edoardo D'Angelo, Nicolò Drago, Nicola Pinamonti +1
We discuss the scaling of the effective action for the interacting scalar quantum field theory on generic spacetimes with Lorentzian signature and in a generic state (including vac…
