Quantum reference frames for spacetime symmetries and large gauge transformations
Daan W. Janssen
Symmetries are a central concept in our understanding of physics. In quantum theories, a quantum reference frame (QRF) can be used to distinguish between observables related by a s…
Semi-local observables, edge modes and quantum reference frames in quantum electromagnetism: an algebraic approach
Christopher J. Fewster, Daan W. Janssen, Kasia Rejzner
Boundaries and corners of spacetime play a vital role in understanding physical concepts including entanglement entropy, the infrared problem in QFT and quantum gravity. Standard l…
Quantum reference frames, measurement schemes and the type of local algebras in quantum field theory
Christopher J. Fewster, Daan W. Janssen, Leon Deryck Loveridge +2
We develop an operational framework, combining relativistic quantum measurement theory with quantum reference frames (QRFs), in which local measurements of a quantum field on a bac…
Super-Gaussian Decay of Exponentials: A Sufficient Condition
Benjamin Hinrichs, Daan Willem Janssen, Jobst Ziebell
In this article, we present a sufficient condition for the exponential to have a tail decay stronger than any Gaussian, where is defined on a locally convex space…
