Fighting non-locality with non-locality: microcausality and boundary conditions in QED
Philipp A. Hoehn, Josh Kirklin
In gauge theories, globally charged observables necessarily depend non-locally on the kinematical fields, with this dependence extending to the asymptotic boundary of spacetime. De…
On the relation between perspective-neutral, algebraic, and effective quantum reference frames
Julian De Vuyst, Philipp A. Hoehn, Artur Tsobanjan
The framework of internal quantum reference frames (QRFs) constitutes a universal toolset for dealing with symmetries in quantum theory and has led to new revelations in quantum gr…
Relational entanglement entropies and quantum reference frames in gauge theories
Goncalo Araujo-Regado, Philipp A. Hoehn, Francesco Sartini
It has been shown that defining gravitational entanglement entropies relative to quantum reference frames (QRFs) intrinsically regularizes them. Here, we demonstrate that such rela…
