Crossed products and quantum reference frames: on the observer-dependence of gravitational entropy
Julian De Vuyst, Stefan Eccles, Philipp A. Hoehn +1
A significant step towards a rigorous understanding of perturbative gravitational entropy was recently achieved by a series of works showing that a proper accounting of gauge invar…
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…
Linearization (in)stabilities and crossed products
Julian De Vuyst, Stefan Eccles, Philipp A. Hoehn +1
Modular crossed product algebras have recently assumed an important role in perturbative quantum gravity as they lead to an intrinsic regularization of entanglement entropies by in…
Exact WKB in all sectors I: Potentials with degenerate saddles
Tatsuhiro Misumi, Cihan Pazarbaşı
We explore the exact-WKB (EWKB) method through the analysis of Airy and Weber types, with an emphasis on the exact quantization of locally harmonic potentials in multiple sectors.…
Holography and the Hilbert Scheme
Samuel Crew, Daniel Zhang, Ziruo Zhang
We elucidate a holographic relationship between the enumerative geometry of the Hilbert scheme of points in the plane , with large, and the entropy of certain…
Gravitational entropy is observer-dependent
Julian De Vuyst, Stefan Eccles, Philipp A. Hoehn +1
In quantum gravity, it has been argued that a proper accounting of the role played by an observer promotes the von Neumann algebra of observables in a given spacetime subregion fro…
