Algebras and Hilbert spaces from gravitational path integrals: Understanding Ryu-Takayanagi/HRT as entropy without AdS/CFT
Eugenia Colafranceschi, Xi Dong, Donald Marolf +1
Recent works by Chandrasekaran, Penington, and Witten have shown in various special contexts that the quantum-corrected Ryu-Takayanagi (RT) entropy (or its covariant Hubeny-Rangama…
A trace inequality for Euclidean gravitational path integrals (and a new positive action conjecture)
Eugenia Colafranceschi, Donald Marolf, Zhencheng Wang
The AdS/CFT correspondence states that certain conformal field theories are equivalent to string theories in a higher-dimensional anti-de Sitter space. One aspect of the correspond…
The Spacetime Geometry of Fixed-Area States in Gravitational Systems
Xi Dong, Donald Marolf, Pratik Rath +2
The concept of fixed-area states has proven useful for recent studies of quantum gravity, especially in connection with gravitational holography. We explore the Lorentz-signature s…
Gravitational thermodynamics without the conformal factor problem: Partition functions and Euclidean saddles from Lorentzian Path Integrals
Donald Marolf
Thermal partition functions for gravitational systems have traditionally been studied using Euclidean path integrals. But in Euclidean signature the gravitational action suffers fr…
The action of HRT-areas as operators in semiclassical gravity
Molly Kaplan, Donald Marolf
We study the action of Hubeny-Rangamani-Takayanagi (HRT) area operators on the covariant phase space of classical solutions. It has been previously proposed that this action genera…
Stability of the microcanonical ensemble in Euclidean Quantum Gravity
Donald Marolf, Jorge E. Santos
This work resolves a longstanding tension between the physically-expected stability of the microcanonical ensemble for gravitating systems and the fact that the known negative mode…
