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…
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…
Lecture Notes on Operator Algebras and Quantum Field Theory
Rainer Verch
Lecture notes prepared for the EMS--IAMP Spring School ``Symmetries and Measurement in Quantum Field Theory''. This set of lecture notes covers four lectures: 1. Operator Algebras…
Probing non-equilibrium steady states of the Klein-Gordon field with Unruh-DeWitt detectors
Albert Georg Passegger, Rainer Verch
We calculate the transition rate of an Unruh-DeWitt detector coupled to a non-equilibrium steady state (NESS) of a free massless scalar field on four-dimensional Minkowski spacetim…
Microlocal Analysis of a Deformed Quantum Field Theory
Rishabh Ballal, Albert Much, Rainer Verch
A deformation technique, known as the warped convolution, takes quantum fields in Minkowski spacetime to quantum fields in noncommutative Minkowski space-time. Since a quantum fiel…
