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

Quantum Field Theory on Curved Noncommutative Spacetimes [PDF]
Proceedings of Corfu Summer Institute on Elementary Particles and Physics - Workshop on Non Commutative Field Theory and Gravity — PoS(CNCFG2010), 2011 We summarize our recently proposed approach to quantum field theory on noncommutative curved spacetimes. We make use of the Drinfel'd twist deformed differential geometry of Julius Wess and his group in order to define an action functional for a real ...

Haag’s theorem in noncommutative quantum field theory [PDF]
Ядерная физика, 2013 Haag’s theorem was extended to the general case of noncommutative quantum field theory when time does not commute with spatial variables. It was proven that if S matrix is equal to unity in one of two theories related by unitary transformation, then the ...

Schwinger Functions in Noncommutative Quantum Field Theory [PDF]
Annales Henri Poincaré, 2009 It is shown that the n-point functions of scalar massive free fields on the noncommutative Minkowski space are distributions which are boundary values of analytic functions.

Test Functions Space in Noncommutative Quantum Field Theory [PDF]
Journal of High Energy Physics, 2007 It is proven that the $\star$-product of field operators implies that the space of test functions in the Wightman approach to noncommutative quantum field theory is one of the Gel'fand-Shilov spaces $S^{\beta}$ with $\beta < 1/2$.

On the Origin of the Harmonic Term in Noncommutative Quantum Field Theory [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2010 The harmonic term in the scalar field theory on the Moyal space removes the UV-IR mixing, so that the theory is renormalizable to all orders. In this paper, we review the three principal interpretations of this harmonic term: the Langmann-Szabo duality ...

Noncommutative quantum field theory: a confrontation of symmetries [PDF]
Journal of High Energy Physics, 2008 The concept of a noncommutative field is formulated based on the interplay between twisted Poincare symmetry and residual symmetry of the Lorentz group.

Quantum Fields on Noncommutative Spacetimes: Theory and Phenomenology [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2010 In the present work we review the twisted field construction of quantum field theory on noncommutative spacetimes based on twisted Poincaré invariance.

Noncommutative and Non-Anticommutative Quantum Field Theory [PDF]
Physics Letters B, 2001 A noncommutative and non-anticommutative quantum field theory is formulated in a superspace, in which the superspace coordinates satisfy noncommutative and non-anticommutative relations.
