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…
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…
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…
Measurement in Quantum Field Theory
Christopher J. Fewster, Rainer Verch
The topic of measurement in relativistic quantum field theory is addressed in this article. Some of the long standing problems of this subject are highlighted, including the incomp…
