Parametric representation of “critical” noncommutative QFT models
We extend the parametric representation of renormalizable non commutative quantum field theories to a class of theories which we call “critical”, because their power counting is definitely more difficult to obtain.This class of theories is important since it includes gauge theories, which should be relevant for the quantum Hall effect.
متن کاملAdmissible Vectors of a Covariant Representation of a Dynamical System
In this paper, we introduce admissible vectors of covariant representations of a dynamical system which are extensions of the usual ones, and compare them with each other. Also, we give some sufficient conditions for a vector to be admissible vector of a covariant pair of a dynamical system. In addition, we show the existence of Parseval frames for some special subspaces of $L^2(G)$ related to...
متن کاملNoncommutative Electrodynamics with covariant coordinates
We study Noncommutative Electrodynamics using the concept of covariant coordinates. We propose a scheme for interpreting the formalism and construct two basic examples, a constant field and a plane wave. Superposing these two, we find a modification of the dispersion relation. Our results differ from those obained via the Seiberg-Witten map. PACS: 11.10.Lm, 11.15.-q, 13.40.-f
متن کاملOn the Correspondence between Poincaré Symmetry of Commutative QFT and Twisted Poincaré Symmetry of Noncommutative QFT
The space-time symmetry of noncommutative quantum field theories with a deformed quantization is described by the twisted Poincaré algebra, while that of standard commutative quantum field theories is described by the Poincaré algebra. Based on the equivalence of the deformed theory with a commutative field theory, the correspondence between the twisted Poincaré symmetry of the deformed theory ...
متن کاملRegularized Algebraic Nets for General Covariant QFT on Differentiable Manifolds
Quantum general relativity may be considered as generally covariant QFT on differentiable manifolds, without any a priori metric structure. The kinematically covariance group acts by general diffeomorphisms on the manifold and by automorphisms on the isotonic net of ∗-algebras encoding the QFT, while the algebra of observables is covariant under the dynamical subgroup of the general diffeomorph...
