LORENTZ INVARIANT AND SUPERSYMMETRIC INTERPRETATION OF NONCOMMUTATIVE QUANTUM FIELD THEORY [PDF]
, 2005 In this paper, using a Hopf-algebraic method, we construct deformed Poincare SUSY algebra in terms of twisted (Hopf) algebra. By adapting this twist deformed super-Poincare algebra as our fundamental symmetry, we can see the consistency between 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 scalar field on a twist-deformed time-oriented, connected and globally hyperbolic Lorentzian manifold ...

On the operator product expansion in noncommutative quantum field theory [PDF]
, 2000 Motivated by the mixing of UV and IR effects, we test the OPE formula in non-commutative field theory. First we look at the renormalization of local composite operators, identifying some of their characteristic IR/UV singularities.

Twists of quantum groups and noncommutative field theory
Journal of Mathematical Sciences, 2007 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 ...

UV/IR duality in noncommutative quantum field theory [PDF]
General Relativity and Gravitation, 2010 We review the construction of renormalizable noncommutative Euclidean ϕ4-theories based on the UV/IR duality covariant modification of the standard field theory, and how the formalism can be extended to scalar field theories defined on noncommutative ...

Matrix Quantum Mechanics and Soliton Regularization of Noncommutative Field Theory [PDF]
, 2004 We construct an approximation to field theories on the noncommutative torus based on soliton projections and partial isometries which together form a matrix algebra of functions on the sum of two circles.

Twisted Poincaré Symmetry and Some Implications on Noncommutative Quantum Field Theory [PDF]
, 2007 The concept of twisted Poincar\'e symmetry, as well as some implications, are reviewed. The spin-statistics relation and the nonlocality of NC QFT are discussed in the light of this quantum symmetry.

, 2014 We present some ideas for a possible Noncommutative Topological Quantum Field Theory (NCTQFT) and Noncommutative Floer Homology (NCFH). Our motivation is two-fold and it comes both from physics and mathematics: On the one hand we argue that NCTQFT is the correct mathematical framework for a quantum field theory of all known interactions in nature ...
