The θ expansion of the Seiberg–Witten map has ambiguities which can be removed by a gauge transformation and/or a field redefinition. In the context of emergent gravity such a field redefinition changes the emerging metric and requires the presence of non-minimal gravitational couplings. It also requires that a real scalar field becomes a scalar density and allows the introduction of a potential. We also find that the potential can have only one term and that a quartic interaction is not… 
Novel ambiguities in the Seiberg-Witten map and the emergent gravity
A bstractA homogeneous part of the Seiberg-Witten gauge equivalence relation for gauge fields can lead to solutions that involve matter fields in such a way that the gauge equivalence and the
Contravariant geometry and emergent gravity from noncommutative gauge theories
We investigate a relation of the contravariant geometry to the emergent gravity from noncommutative gauge theories. We give a refined formulation of the contravariant gravity and provide solutions to
Charged rotating BTZ black holes in noncommutative spaces and torsion gravity.
We consider charged rotating BTZ black holes in noncommutative space by use of Chern-Simons theory formulation of $2+1$ dimensional gravity. The noncommutativity between the radial and the angular
An Axiomatization Proposal and a Global Existence Theorem for Strong Emergence Between Parameterized Lagrangian Field Theories
In this paper we propose an axiomatization for the notion of strong emergence phenomenon between field theories depending on additional parameters, which we call parameterized field theories. We
Towards Axiomatization and General Results on Strong Emergence Phenomena Between Lagrangian Field Theories
In this paper we propose a formal definition of what is a strong emergence phenomenon between two parameterized field theories and we present sufficient conditions ensuring the existence of such
Calabi-Yau manifolds from noncommutative Hermitian U(1) instantons
We show that Calabi-Yau manifolds are emergent from the commutative limit of six-dimensional noncommutative Hermitian $U(1)$ instantons. Therefore, we argue that the noncommutative Hermitian $U(1)$
On the Non-Flatness Nature of Noncommutative Minkowski Spacetime
: In the framework of twisted-diffeomorphism approach to noncommutative gravity with canonical/Moyal-Weyl type noncommutative (NC) coordinate structure, we show that the NC Minkowski spacetime


Noncommutative field theories and gravity
We find a closed form for Seiberg–Witten (SW) map between ordinary and noncommutative (NC) Dirac–Born–Infeld actions. We show that NC Maxwell action after the exact SW map can be regarded as ordinary
Instantons, Twistors, and Emergent Gravity
Motivated by potential applications to holography on space-times of positive curvature, and by the successful twistor description of scattering amplitudes, we propose a new dual matrix formulation of
Seiberg-Witten Map for Superfields on Canonically Deformed N=1, d=4 Superspace
In this paper we construct Seiberg-Witten maps for superfields on canonically deformed N = 1, d = 4 Minkowski and euclidean superspace. On Minkowski superspace we show that the Seiberg-Witten map is
TOPICAL REVIEW: Emergent geometry and gravity from matrix models: an introduction
An introductory review to emergent noncommutative gravity within Yang–Mills matrix models is presented. Spacetime is described as a noncommutative brane solution of the matrix model, i.e. as a
String theory and noncommutative geometry
We extend earlier ideas about the appearance of noncommutative geometry in string theory with a nonzero B-field. We identify a limit in which the entire string dynamics is described by a minimally
Towards integrability for AdS3/CFT2
In this thesis we consider certain supersymmetric string theories on curved backgrounds containing the three-dimensional anti-de Sitter space, AdS3. On the one hand, these are gravity theories in
Dynamics of strings in noncommutative gauge theory
We continue our study of solitons in noncommutative gauge theories and present an extremely simple BPS solution of = 4 U(1) noncommutative gauge theory in 4 dimensions, which describes N infinite
Emergent spacetime and the origin of gravity
We present an exposition on the geometrization of the electromagnetic force. We show that, in noncommutative (NC) spacetime, there always exists a coordinate transformation to locally eliminate the
