Causal measurement in quantum field theory: spacetime
Robert Oeckl
We provide a framework and explicit construction for the regularized measurement of a large class of spacetime-localized observables in bosonic quantum field theory. The measuremen…
Towards local and compositional measurements in quantum field theory
Robert Oeckl, Adamantia Zampeli
A universal framework for the joint measurement of multiple localized observables in quantum field theory satisfying spacetime locality and compositionality is still lacking. We pr…
Spectral decomposition of field operators and causal measurement in quantum field theory
Robert Oeckl
We construct the spectral decomposition of field operators in bosonic quantum field theory as a limit of a strongly continuous family of positive-operator-valued measure decomposit…
A time operator and the time-of-arrival problem in quantum field theory
Daniele Colosi, Robert Oeckl
The Newton-Wigner states and operator are widely accepted to provide an adequate notion of spatial localization of a particle in quantum field theory on a spacelike hypersurface. R…
Interaction of evanescent particles with an Unruh-DeWitt detector
Daniele Colosi, Robert Oeckl, Adamantia Zampeli
We demonstrate that the recently introduced evanescent particles of a massive scalar field can be emitted and absorbed by an Unruh-DeWitt detector. In doing so the particles carry…
Compositional Quantum Field Theory: An axiomatic presentation
Robert Oeckl, Juan Orendain Almada
We introduce Compositional Quantum Field Theory (CQFT) as an axiomatic model of Quantum Field Theory, based on the principles of locality and compositionality. Our model is a refin…
