We discuss the effects that a noncommutative geometry induced by a Drinfeld twist has on physical theories. We systematically deform all products and symmetries of the theory. We discuss noncommutative classical mechanics, in particular its deformed Poisson bracket and hence time evolution and symmetries. The twisting is then extended to classical fields, and then to the main interest of this work: quantum fields. This leads to a geometric formulation of quantization on noncommutative space… 
Algebraic approach to quantum field theory on a class of noncommutative curved spacetimes
In this article we study the quantization of a free real scalar field on a class of noncommutative manifolds, obtained via formal deformation quantization using triangular Drinfel’d twists. We
Noncommutative deformations of quantum field theories, locality, and causality
We investigate noncommutative deformations of quantum field theories for different star products, particularly emphasizing the locality properties and the regularity of the deformed fields. Using
On second quantization on noncommutative spaces with twisted symmetries
By the application of the general twist-induced -deformation procedure we translate second quantization of a system of bosons/fermions on a symmetric spacetime into a noncommutative language. The
Duality and braiding in twisted quantum field theory
We re-examine various issues surrounding the definition of twisted quantum field theories on flat noncommutative spaces. We propose an interpretation based on nonlocal commutative field redefinitions
Star product geometries
We consider noncommutative geometries obtained from a triangular Drinfeld twist. This allows us to construct and study a wide class of noncommutative manifolds and their deformed Lie algebras of
Symmetry Reduction in Twisted Noncommutative Gravity with Applications to Cosmology and Black Holes
As a preparation for a mathematically consistent study of the physics of symmetric spacetimes in a noncommutative setting, we study symmetry reductions in deformed gravity. We focus on deformations
Noncommutative spaces with twisted symmetries and second quantization
In a minimalistic view, the use of noncommutative coordinates can be seen just as a way to better express non-local interactions of a special kind: 1-particle solutions (wavefunctions) of the
Wedge locality and asymptotic commutativity
In this paper, we study twist deformed quantum field theories obtained by combining the Wightman axiomatic approach with the idea of spacetime noncommutativity. We prove that the deformed fields with
Twisted statistics and the structure of Lie-deformed Minkowski spaces
We show that the realizations of noncommutative coordinates that are linear in the Lorentz generators form a closed Lie algebra under certain conditions. The star product and the coproduct for the
Inequivalence of quantum field theories on noncommutative spacetimes: Moyal versus Wick-Voros planes
In this paper, we further develop the analysis started in an earlier paper on the inequivalence of certain quantum field theories on noncommutative spacetimes constructed using twisted fields. The


Noncommutative Field Theory from twisted Fock space
We construct a quantum field theory in noncommutative space time by twisting the algebra of quantum operators (especially, creation and annihilation operators) of the corresponding quantum field
Symmetry, gravity and noncommutativity
We review some aspects of the implementation of spacetime symmetries in noncommutative field theories, emphasizing their origin in string theory and how they may be used to construct theories of
Noncommutative spacetime symmetries : Twist versus covariance
We prove that the Moyal product is covariant under linear affine spacetime transformations. From the covariance law, by introducing an (x, Theta)-space where the spacetime coordinates and the
2 00 0 Untwisting Noncommutative R d and the Equivalence of Quantum Field Theories
We show that there is a duality exchanging noncommutativity and non-trivial statistics for quantum field theory on R. Employing methods of quantum groups, we observe that ordinary and noncommutative

Remarks on twisted noncommutative quantum field theory
We review recent results on twisted noncommutative quantum field theory by embedding it into a general framework for the quantization of systems with a twisted symmetry. We discuss commutation
Noncommutative deformation of four-dimensional Einstein gravity
We construct a model for noncommutative gravity in four dimensions, which reduces to the Einstein–Hilbert action in the commutative limit. Our proposal is based on a gauge formulation of gravity with
