Relative entropy for in the Rindler wedge
Markus B. Fröb, Albert Much, Kyriakos Papadopoulos
We consider the relative entropy between the vacuum and a coherent state in the Rindler wedge for an interacting theory to first order in . We construct the perturbati…
A UV-Finite Ryu-Takayanagi Relation from Relative Entropy in AdS/CFT
Albert Much, Philipp Dorau, Leonardo Sangaletti +1
We establish a Ryu-Takayanagi (RT) relation in AdS/CFT using \emph{relative entropy} as the central object, in place of the ultraviolet-divergent von Neumann entanglement e…
Noncommutative QFT and Relative Entropy on Axisymmetric Bifurcate Killing Horizons
Philipp Dorau, Albert Much, Rainer Verch
We construct a deformed algebraic quantum field theory on bifurcate Killing horizons in stationary axisymmetric spacetimes. The deformation is generated by the commuting actions of…
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…
A Quantum Energy Inequality for a Non-commutative QFT
Harald Grosse, Albert Much
We present a quantum energy inequality (QEI) for quantum field theories formulated in non-commutative spacetimes, extending fundamental energy constraints to this generalized geome…
