Mapping the Infrared Phase Space of Gravity to Finite Subregions
Luca Ciambelli, Temple He, Marc S. Klinger +1
We construct the phase space for an arbitrary cut of a null hypersurface in Minkowski spacetime and demonstrate that it is symplectomorphic to the infrared phase space of asymptoti…
Effective density matrix for vacua in asymptotically flat gravity
Temple He, Prahar Mitra, Kathryn M. Zurek
We explicitly construct the density matrix associated to the vacuum state of a large spherically symmetric causal diamond of area in four-dimensional asymptotically flat gravit…
From Asymptotically Flat Gravity to Finite Causal Diamonds
Luca Ciambelli, Temple He, Kathryn M. Zurek
We demonstrate that the phase space of the soft sector of asymptotically flat gravity in four spacetime dimensions can be identified with that of a spherically symmetric finite cas…
Thermodynamics of a Spherically Symmetric Causal Diamond in Minkowski Spacetime
Kwinten Fransen, Temple He, Kathryn M. Zurek
We compute a gravitational on-shell action of a finite, spherically symmetric causal diamond in -dimensional Minkowski spacetime, finding it is proportional to the area of t…
Quantum Area Fluctuations from Gravitational Phase Space
Luca Ciambelli, Temple He, Kathryn M. Zurek
We study the gravitational phase space associated to a stretched horizon within a finite-sized causal diamond in -dimensional spacetimes. By imposing the Raychaudhuri equati…
Quantum Mechanics of a Spherically Symmetric Causal Diamond in Minkowski Spacetime
Mathew W. Bub, Temple He, Prahar Mitra +2
We construct the phase space of a spherically symmetric causal diamond in -dimensional Minkowski spacetime. Utilizing the covariant phase space formalism, we identify the re…
