Issues of duality on non-commutative manifolds: the {\it non-equivalence} between self-dual and topologically massive models

TL;DR

This paper investigates duality in non-commutative 3D models, revealing that the non-commutative self-dual model is not dual to the Maxwell-Chern-Simons model, but to a deformed version, challenging previous assumptions.

Contribution

It demonstrates that the non-commutative self-dual model is dual to a deformed Maxwell-Chern-Simons model, not the standard one, providing insights beyond finite-order expansions.

Findings

The non-commutative SD model is not dual to the standard MCS model.

A deformed MCS model is identified as dual to the NC-SD model.

Results hold beyond finite-order Seiberg-Witten expansions.

Abstract

We study issues of duality and dual equivalence in non-commutative manifolds. In particular the question of dual equivalence for the actions of the non-commutative extensions of the self-dual model (NC-SD) in 3D space-time and the Maxwell-Chern-Simons model (MCS-SD) is investigate. We show that former model {\it is not} dual equivalent the non-commutative extension of the Maxwell-Chern-Simons model, as widely believed, but a to deformed version of it that is disclosed here. Our results are not restrict to any finite order in the Seiberg-Witten expansion involving the non-commutative parameter $\theta$.
