Remarks on some new models of interacting quantum fields with indefinite metric
S. Albeverio, H. Gottschalk, J. -L. Wu
We study quantum field models in indefinite metric. We introduce the modified Wightman axioms of Morchio and Strocchi as a general framework of indefinite metric quantum field theo…
Indefinite metric
H. Gottschalk
The quantization of gauge fields with the help of the Gupta-Bleuler formalism is reviewed.
Nontrivial models with indefinite metric
S. Albeverio, H. Gottschalk
The non perturbative construction of quantum field models with nontrivial scattering in arbitrary dimension of the underlying Minkowski space-time is much more simple in the fr…
Scattering theory for quantum fields with indefinite metric
S. Albeverio, H. Gottschalk
In this work, we discuss the scattering theory of local, relativistic quantum fields with indefinite metric. Since the results of Haag--Ruelle theory do not carry over to the case…
Representing Euclidean quantum fields as scaling limit of particle systems
S. Albeverio, H. Gottschalk, M. -w. Yoshida
We give a new representation of Euclidean quantum fields as scaling limits of systems of interacting, continuous, classical particles in the grand canonical ensemble.
Partly divisible probability measures on locally compact Abelian groups
S. Albeverio, H. Gottschalk, J. -L. Wu
A notion of admissible probability measures on a locally compact Abelian group (LCA-group) with connected dual group $\hat G=\R^d\times \T^n$ is defined. To such a measure…
