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 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…
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…
The Relative Fermionic Entropy in Two-Dimensional Rindler Spacetime
Felix Finster, Albert Much
The fermionic relative entropy in two-dimensional Rindler spacetime is studied using both modular theory and the reduced one-particle density operators. The methods and results are…
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…
