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…
Local Structure of Sprinkled Causal Sets
Christopher J. Fewster, Eli Hawkins, Christoph Minz +1
We describe numerical and analytical investigations of causal sets sprinkled into spacetime manifolds. The first part of the paper is a numerical study of finite causal sets sprink…
Asymptotic symmetries in the BV-BFV formalism
Kasia Rejzner, Michele Schiavina
We show how to derive asymptotic charges for field theories on manifolds with "asymptotic" boundary, using the BV-BFV formalism. We also prove that the conservation of said charges…
Algebraic Classical and Quantum Field Theory on Causal Sets
Edmund Dable-Heath, Christopher J. Fewster, Kasia Rejzner +1
The framework of perturbative algebraic quantum field theory (pAQFT) is used to construct QFT models on causal sets. We discuss various discretised wave operators, including a new…
Locality and causality in perturbative AQFT
Kasia Rejzner
In this paper we discuss how seemingly different notions of locality and causality in quantum field theory can be unified using a non-abelian generalization of the Hammerstein prop…
Algebraic Quantum Field Theory -- an introduction
Christopher J. Fewster, Kasia Rejzner
We give a pedagogical introduction to algebraic quantum field theory (AQFT), with the aim of explaining its key structures and features. Topics covered include: algebraic formulati…
