κ -Poincaré comodules, braided tensor products, and noncommutative quantum field theory [PDF]
, 2021 We discuss the obstruction to the construction of a multiparticle field theory on a κ-Minkowski noncommutative spacetime: the existence of multilocal functions which respect the deformed symmetries of the problem. This construction is only possible for a

Braided quantum electrodynamics
Journal of High Energy Physics, 2023 The homotopy algebraic formalism of braided noncommutative field theory is used to define the explicit example of braided electrodynamics, that is, U(1) gauge theory minimally coupled to a Dirac fermion.

Quantum theory of noncommutative fields [PDF]
Journal 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 ...

An Introduction to Noncommutative Physics
Physics, 2023 Noncommutativity in physics has a long history, tracing back to classical mechanics. In recent years, many new developments in theoretical physics, and in practical applications rely on different techniques of noncommutative algebras.

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

Quantum Field Theory on Noncommutative Curved Space-times and Noncommutative Gravity
, 2021 In the noncommutative gauge-theoretical formulation of Langman and Szabo, apparently it appears that the torsion generated there is a generalized one i.e. it may containvector, axial vector and tensor components.

Renormalizable noncommutative quantum field theory [PDF]
General Relativity and Gravitation, 2010 We discuss special Euclidean noncommutative phi(4)-quantum field theory models in two and four dimensions They are examples of renormalizable field theories. Using a Ward identity, it has been shown, that the beta function for the coupling constant vanishes to all orders in perturbation theory.

Noncommutative deformations of Wightman quantum field theories [PDF]
Journal 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

Aspects of Nonrelativistic Strings
Frontiers in Physics, 2022 We review recent developments on nonrelativistic string theory. In flat spacetime, the theory is defined by a two-dimensional relativistic quantum field theory with nonrelativistic global symmetries acting on the worldsheet fields.
