Inverse Scattering and Locality in Integrable Quantum Field Theories
Sabina Alazzawi, Gandalf Lechner
We present a solution method for the inverse scattering problem for integrable two-dimensional relativistic quantum field theories, specified in terms of a given massive single par…
Deformations of quantum field theories on spacetimes with Killing vector fields
Claudio Dappiaggi, Gandalf Lechner, Eric Morfa-Morales
The recent construction and analysis of deformations of quantum field theories by warped convolutions is extended to a class of curved spacetimes. These spacetimes carry a family o…
Warped Convolutions, Rieffel Deformations and the Construction of Quantum Field Theories
Detlev Buchholz, Gandalf Lechner, Stephen J. Summers
Warped convolutions of operators were recently introduced in the algebraic framework of quantum physics as a new constructive tool. It is shown here that these convolutions provide…
Wedge-Local Quantum Fields and Noncommutative Minkowski Space
Harald Grosse, Gandalf Lechner
Within the setting of a recently proposed model of quantum fields on noncommutative Minkowski spacetime, the consequences of the consistent application of the proper, untwisted Poi…
On the Construction of Quantum Field Theories with Factorizing S-Matrices
Gandalf Lechner
The subject of this thesis is a novel construction method for interacting relativistic quantum field theories on two-dimensional Minkowski space. The input in this construction is…
