1203.1992 (Jia-Hui Huang et al.)

Microcausality of spin-induced noncommutative theories    [PDF]

Jia-Hui Huang, Weijian Wang
In this brief report, the microcausility of quantum ?eld theory on spin-induced noncom- mutative spacetime is discussed. It is found that for spacelike seperation the microcausality is not obeyed by the theory generally. It means that Lorentz covariance can not guaran- tee microcausality in quantum ?eld thoery. We also give some comments about quantum ?eld thoeries on such noncommutative spacetime and the relations between noncommutative spacetime and causality.
