On the equivalence of AQFTs and prefactorization algebras
Marco Benini, Victor Carmona, Alastair Grant-Stuart +1
This paper revisits the equivalence problem between algebraic quantum field theories and prefactorization algebras defined over globally hyperbolic Lorentzian manifolds. We develop…
Haag-Kastler stacks
Marco Benini, Alastair Grant-Stuart, Alexander Schenkel
This paper provides an alternative implementation of the principle of general local covariance for algebraic quantum field theories (AQFTs) which is more flexible than the original…
Obstructions to the existence of Møller maps
Marco Benini, Alastair Grant-Stuart, Giorgio Musante +1
Møller maps are identifications between the observables of a perturbatively interacting physical system and the observables of its underlying free (i.e. non-interacting) system. T…
Lorentzian bordisms in algebraic quantum field theory
Severin Bunk, James MacManus, Alexander Schenkel
It is shown that every algebraic quantum field theory has an underlying functorial field theory which is defined on a suitable globally hyperbolic Lorentzian bordism pseudo-categor…
