Superluminal local operations in quantum field theory: A ping-pong ball test
Albert Much, Rainer Verch
It is known that in quantum field theory, localized operations, e.g.\ given by unitary operators in local observable algebras, may lead to non-causal, or superluminal, state change…

Relative Entropy of Fermion Excitation States on the CAR Algebra
Stefano Galanda, Albert Much, Rainer Verch
The relative entropy of certain states on the algebra of canonical anticommutation relations (CAR) is studied in the present work. The CAR algebra is used to describe fermionic deg…

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…
