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…

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…
