چکیده
We study the Moyal commutators and their expectation values between vacuum states and non-vacuum states for free scalar field on noncommutative spacetime. Then from the Moyal commutators, we find that the microcausality is satisfied for the linear operators of the free scalar field on noncommutative spacetime. We construct the Feynman propagator of Moyal star-product for noncommutative scalar field theory. PACS numbers: 11.10.Nx, 03.70.+k

We study the Moyal anticommutators and their expectation values between vacuum states and non-vacuum states for Dirac fields on noncommutative spacetime. Then we construct the propagators of Moyal star-products for Dirac fields on noncommutative spacetime. We find that the propagators of Moyal star-products for Dirac fields are equal to the propagators of Dirac fields on ordinary commutative sp...
متن کاملMicrocausality violation of scalar field on noncommutative spacetime with the time-space noncommutativity
Quantum field theories on noncommutative spacetime have many different properties from those on commutative spacetime. In this paper, we study the microcausality of free scalar field on noncommutative spacetime. We expand the scalar field in the form of usual Lorentz invariant measure in noncommutative spacetime. Then we calculate the expectation values of the Moyal commutators for the quadrati...
متن کاملMicrocausality of scalar field on noncommutative spacetime
We analyze the microcausality of free scalar field on noncommutative spacetime. To adopt the usual Lorentz invariant spectral measure, through the result of the expectation values of the Moyal commutators, for the quadratic operators such as φ(x) ⋆ φ(x), π(x, t) ⋆ π(x, t), ∂iφ(x, t) ⋆ ∂iφ(x, t), and ∂iφ(x, t) ⋆ π(x, t), we obtain that for the case θ = 0 of the spacetime noncommutativity, the mi...
متن کاملQuantum motion equation and Poincaré translation invariance of noncommutative field theory
We study the Moyal commutators and their expectation values between vacuum states and non-vacuum states for noncommutative scalar field theory. For noncommutative φ⋆4 scalar field theory, we derive its energy-momentum tensor from translation transformation and Lagrange field equation. We generalize the Heisenberg and quantum motion equations to the form of Moyal star-products for noncommutative...
