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…
