The role of the field redefinition in noncommutative Maxwell theory
I. Fruhwirth, J. M. Grimstrup, Z. Morsli +2
We discuss -deformed Maxwell theory at first order in with the help of the Seiberg-Witten (SW) map. With an appropriate field redefinition consistent with the SW-map we anal…

Deformed QED via Seiberg-Witten Map
A. A. Bichl, J. M. Grimstrup, L. Popp +2
With the help of the Seiberg-Witten map for photons and fermions we define a theta-deformed QED at the classical level. Two possibilities of gauge-fixing are discussed. A possible…

The energy-momentum tensor on noncommutative spaces - some pedagogical comments
A. Gerhold, J. Grimstrup, H. Grosse +3
We present the discussion of the energy-momentum tensor of the scalar - theory on a noncommutative space. The Noether procedure is performed at the operator level. Additionall…
