We propose a measurement theory for quantum fields based on measurements made with
localized nonrelativistic systems that couple covariantly to quantum fields (like the Unruh …

The deflection of light in the gravitational field of the Sun is one of the most fundamental
consequences for general relativity as well as one of its classical tests first performed by …

We develop an operational framework, combining relativistic quantum measurement theory
with quantum reference frames (QRFs), in which local measurements of a quantum field on …

The process of quantum measurement is considered in the algebraic framework of quantum
field theory on curved spacetimes. Measurements are carried out on one quantum field …

This paper provides a review of the literature on rigorous definitions and constructions in
quantum field theory (QFT), spanning the period of seven decades. Compared with the …

Matter-wave interferometers with large momentum transfers, irrespective of specific
implementations, will face a universal dephasing due to relative accelerations between the …

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 formulations of …

Abstract Quantum Energy Inequalities (QEIs) are lower bounds on local averages of energy
densities and related quantities in quantum field theory (QFT). They replace the classical …

The topic of measurement in relativistic quantum field theory is addressed in this article.
Some of the long standing problems of this subject are highlighted, including the …

A recently introduced functional renormalization group (RG) provides a new tool to explore
nonperturbative and covariant RG flows in Lorentzian spacetimes. We apply it for the first …
