Irreducibility of the set of field operators in Noncommutative Quantum Field Theory [PDF]

open access: green, 2012
Аннотация Irreducibility of the set of quantum field operators has been proved in noncommutative quantum field theory in the general case when time does not commute with spatial variables. PACS: 11.10.Cd, 11.10.Nx.

3D Quantum Gravity and Effective Noncommutative Quantum Field Theory [PDF]

open access: greenPhysical Review Letters, 2006
We show that the effective dynamics of matter fields coupled to 3D quantum gravity is described after integration over the gravitational degrees of freedom by a braided noncommutative quantum field theory symmetric under a kappa deformation of the ...

Unitary quantum field theory on the noncommutative Minkowski space [PDF]

open access: greenFortschritte der Physik, 2003
AbstractThis is an exposition of joint work with S. Doplicher, K. Fredenhagen, and Gh. Piacitelli [1]. The violation of unitarity found in quantum field theory on noncommutative spacetimes in the context of the so‐called modified Feynman rules is linked to the notion of time ordering implicitly used in the assumption that perturbation theory may be ...

𝒫𝒯-symmetric quantum field theory on the noncommutative spacetime [PDF]

open access: greenModern Physics Letters A, 2019
We consider the [Formula: see text]-symmetric quantum field theory on the noncommutative spacetime with angular twist and construct its pseudo-Hermitian interpretation.

Heisenberg Evolution in a Quantum Theory of Noncommutative Fields [PDF]

open access: bronzeJournal of High Energy Physics, 2004
A quantum theory of noncommutative fields was recently proposed by Carmona, Cortez, Gamboa and Mendez (hep-th/0301248). The implications of the noncommutativity of the fields, intended as the requirements $[ , ^{+}]= ^{3}(x-x^{\prime}), [ , ^{+}]=B ^{3}(x-x^{\prime}) $, were analyzed on the basis of an analogy with previous results on the so ...

NONCOMMUTATIVE FIELD THEORY AND THE DYNAMICS OF QUANTUM HALL FLUIDS [PDF]

open access: greenInternational Journal of Modern Physics A, 2002
We study the spectrum of density fluctuations of fractional Hall fluids in the context of the noncommutative hydrodynamical model of Susskind. We show that, within the weak-field expansion, the leading correction to the noncommutative Chern–Simons Lagrangian (a Maxwell term in the effective action), destroys the incompressibility of the Hall fluid due
