Relational Dynamics with Periodic Clocks
Leonardo Chataignier, Philipp A. Hoehn, Maximilian P. E. Lock +1
We discuss a systematic way in which a relational dynamics can be established relative to periodic clocks both in the classical and quantum theories, emphasising the parallels betw…

Soft edges: the many links between soft and edge modes
Goncalo Araujo-Regado, Philipp A. Hoehn, Francesco Sartini +1
Boundaries in gauge theory and gravity give rise to symmetries and charges at both finite and asymptotic distance. Due to their structural similarities, it is often held that soft…

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…
