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…
