Quantum theory of noncommutative fields [PDF]

open access: yesJournal of High Energy Physics, 2003
Generalizing the noncommutative harmonic oscillator construction, we propose a new extension of quantum field theory based on the concept of "noncommutative fields". Our description permits to break the usual particle-antiparticle degeneracy at the dispersion relation level and introduces naturally an ultraviolet and an infrared cutoff ...

Nested Catalan tables and a recurrence relation in noncommutative quantum field theory [PDF]

open access: yesAnnales de l'Institut Henri Poincaré D, 2019
Correlation functions in a dynamic quartic matrix model are obtained from the two-point function through a recurrence relation. This paper gives the explicit solution of the recurrence by mapping it bijectively to a two-fold nested combinatorial ...

EXISTENCE OF ASYMPTOTIC EXPANSIONS IN NONCOMMUTATIVE QUANTUM FIELD THEORIES [PDF]

open access: greenReviews in Mathematical Physics, 2008
Starting from the complete Mellin representation of Feynman amplitudes for noncommutative vulcanized scalar quantum field theory, introduced in a previous publication, we generalize to this theory the study of asymptotic behaviors under scaling of arbitrary subsets of external invariants of any Feynman amplitude.

Twists of quantum groups and noncommutative field theory [PDF]

open access: greenJournal of Mathematical Sciences, 2006
The role of quantum universal enveloping algebras of symmetries in constructing a noncommutative geometry of space-time and corresponding field theory is discussed. It is shown that in the framework of the twist theory of quantum groups, the noncommutative (super) space-time defined by coordinates with Heisenberg commutation relations, is (super ...

Classical Theorems in Noncommutative Quantum Field Theory [PDF]

open access: green, 2006
Classical results of the axiomatic quantum field theory - Reeh and Schlieder's theorems, irreducibility of the set of field operators and generalized Haag's theorem are proven in SO(1,1) invariant quantum field theory, of which an important example is noncommutative quantum field theory.

Noncommutative deformations of Wightman quantum field theories [PDF]

open access: yesJournal of High Energy Physics, 2008
Quantum field theories on noncommutative Minkowski space are studied in a model-independent setting by treating the noncommutativity as a deformation of quantum field theories on commutative space. Starting from an arbitrary Wightman theory, we consider special vacuum representations of its Weyl-Wigner deformed counterpart. In such representations, the

Lorentz-breaking weighted measures as quantum field theory regulators

open access: yesPhysics Letters B, 2022
In this work we develop a re-formulation of quantum field theory through the more general weighted measures that the definition of quantum fields allows, and that violate explicitly the Lorentz symmetry; this approach provides finite answers for the long-
