Noncommutative field theory

MR Douglas, NA Nekrasov - Reviews of Modern Physics, 2001 - APS

coordinates, starting with the basics and covering most of the active directions of research …

Quantum field theory on noncommutative spaces

RJ Szabo - Physics Reports, 2003 - Elsevier
A pedagogical and self-contained introduction to noncommutative quantum field theory is
presented, with emphasis on those properties that are intimately tied to string theory and …

Symmetry, gravity and noncommutativity

RJ Szabo - Classical and Quantum Gravity, 2006 - iopscience.iop.org
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 …

Nonabelian noncommutative gauge theory via noncommutative extra dimensions

B Jurčo, P Schupp, J Wess - Nuclear Physics B, 2001 - Elsevier
The concept of covariant coordinates on noncommutative spaces leads directly to gauge
theories with generalized noncommutative gauge fields of the type that arises in string …

Observables of non-commutative gauge theories

DJ Gross, A Hashimoto, N Itzhaki - arXiv preprint hep-th/0008075, 2000 - arxiv.org
We construct gauge invariant operators in non-commutative gauge theories which in the IR
reduce to the usual operators of ordinary field theories (eg F^ 2). We show that in the deep …

Emergent gravity from noncommutative space–time

HS Yang - International Journal of Modern Physics A, 2009 - World Scientific
We showed before that self-dual electromagnetism in noncommutative (NC) space–time is
equivalent to self-dual Einstein gravity. This result implies a striking picture about gravity …

Quantum gravity, field theory and signatures of noncommutative spacetime

RJ Szabo - General Relativity and Gravitation, 2010 - Springer
A pedagogical introduction to some of the main ideas and results of field theories on
quantized spacetimes is presented, with emphasis on what such field theories may teach us …

∗-Trek II:∗ n operations, open Wilson lines and the Seiberg–Witten map

H Liu - Nuclear Physics B, 2001 - Elsevier
Generalizations of the∗-product (eg, n-ary∗ n operations) appear in various places in the

Deformed superspace, 𝒩= 1/2 supersymmetry & (non) renormalization theorems

R Britto, B Feng, SJ Rey - Journal of High Energy Physics, 2003 - iopscience.iop.org
We consider a deformed superspace in which the coordinates θ do not anticommute, but
satisfy a Clifford algebra. We present results on the properties of Script N= 1/2 …
