Edge modes as reference frames and boundary actions from post-selection
Sylvain Carrozza, Philipp A. Hoehn
We introduce a general framework realizing edge modes in (classical) gauge field theory as dynamical reference frames, an often suggested interpretation that we make entirely expli…
Internal quantum reference frames for finite Abelian groups
Philipp A. Hoehn, Marius Krumm, Markus P. Mueller
Employing internal quantum systems as reference frames is a crucial concept in quantum gravity, gauge theories and quantum foundations whenever external relata are unavailable. In…
Quantum Relativity of Subsystems
Shadi Ali Ahmad, Thomas D. Galley, Philipp A. Hoehn +2
One of the most basic notions in physics is the partitioning of a system into subsystems, and the study of correlations among its parts. In this work, we explore these notions in t…
