Quantum Gravity, Hydrodynamics and Emergent Cosmology: A Collection of Perspectives
Jibril Ben Achour, Dario Benedetti, Martin Bojowald +17
This collection of perspective pieces captures recent advancements and reflections from a dynamic research community dedicated to bridging quantum gravity, hydrodynamics, and emerg…
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…
Generalised second law beyond the semiclassical regime
Josh Kirklin
We prove that the generalised second law (GSL), with an appropriate modification, holds in perturbative gravity to all orders beyond the semiclassical limit and without a UV cutoff…
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…
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…
