Deformations of quantum field theories on de Sitter spacetime
Eric Morfa-Morales
TL;DR
This paper explores how quantum field theories with U(1) symmetry on de Sitter space can be deformed to become wedge-local, revealing new models that differ from the original, especially for free charged Dirac fields.
Contribution
It introduces a novel deformation method combining internal symmetry and boost actions, producing wedge-local models that are not isomorphic to the original theories.
Findings
Deformed theories are wedge-local and non-isomorphic to initial theories.
The deformation affects models derived from CAR-algebra inclusions.
Explicit analysis of free charged Dirac field deformations.
Abstract
Quantum field theories on de Sitter spacetime with global U(1) gauge symmetry are deformed using the joint action of the internal symmetry group and a one-parameter group of boosts. The resulting theory turns out to be wedge-local and non-isomorphic to the initial one for a class of theories, including the free charged Dirac field. The properties of deformed models coming from inclusions of CAR-algebras are studied in detail.
