Title: Measurement Schemes for Interacting Quantum Fields
Abstract: A local, covariant description of the measurement process in relativistic quantum field theory was recently developed by Fewster and Verch. In this framework, a target quantum field theory is measured indirectly by means of a coupling to a probe field theory in a compact region of spacetime. For field theories admitting a description by a Lagrangian, the coupled theory differs from the uncoupled one the addition of an interaction term. To date, concrete implementations of the Fewster-Verch framework have been exemplified by an uncoupled theory of free scalar fields, with a coupled theory described by a linear interaction term. In this talk, we discuss how methods of perturbative algebraic quantum field theory can be applied to analyse measurement schemes for interacting quantum fields and how these techniques allow for explicit computation of quantities of interest.
