From Quantum Relative Entropy to the Semiclassical Einstein Equations
Philipp Dorau, Albert Much
We provide arguments indicating that the semiclassical Einstein equations follow from quantum relative entropy and its proportionality to an area variation. Using modular theory, w…

Local Expansion Mechanisms for Quantum-Scale Wormholes
Philipp Dorau, Albert Much
Quantum models of spacetime have been conjectured to hypothetically allow for the formation of Planck scale wormholes. Building on the proposal of Morris, Thorne, and Yurtsever tha…
