A Goldstone Theorem in Thermal Relativistic Quantum Field Theory
Christian D. Jaekel, Walter F. Wreszinski
We prove a Goldstone Theorem in thermal relativistic quantum field theory, which relates spontaneous symmetry breaking to the rate of space-like decay of the two-point function. Th…

On the mixing property for a class of states of relativistic quantum fields
Christian D. Jaekel, Heide Narnhofer, Walter F. Wreszinski
Let be a factor state on the quasi-local algebra of observables generated by a relativistic quantum field, which in addition satisfies certain regularity conditions (…
