The two-sided Bogoliubov inequality in von Neumann algebras conceptualizes the free energy--quantum correlations link
Benedikt M. Reible, Albert Much, Rainer Verch +2
The quantum-mechanical two-sided Bogoliubov inequality provides upper and lower bounds for the free energy required to separate a system of interacting particles into independent s…
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 perturbativel…
A UV-Finite Refinement of the Ryu-Takayanagi Relation in AdS/CFT
Albert Much, Philipp Dorau, Leonardo Sangaletti +1
We establish a refined Ryu--Takayanagi (RT) relation in AdS/CFT using \emph{relative entropy} as the central object, in place of the ultraviolet-divergent von Neumann entan…
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…
A proposal for the algebra of a novel noncommutative spacetime
Markus B. Fröb, Albert Much, Kyriakos Papadopoulos
We investigate the quantum structure of spacetime at fundamental scales via a novel, Lorentz-invariant noncommutative coordinate framework. Building on insights from noncommutative…
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…
