# Inequivalence of quantum field theories on noncommutative spacetimes: Moyal versus Wick-Voros planes

@article{Balachandran2009InequivalenceOQ, title={Inequivalence of quantum field theories on noncommutative spacetimes: Moyal versus Wick-Voros planes}, author={Aiyalam P. Balachandran and Alberto Ibort and Giuseppe Marmo and Mario Martone}, journal={Physical Review D}, year={2009}, volume={81}, pages={085017} }

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 issue is of physical importance. Thus it is well known that the commutation relations among spacetime coordinates, which define a noncommutative spacetime, do not constrain the deformation induced on the algebra of functions uniquely. Such deformations are all mathematically equivalent in a very…
