Microcausality of Dirac field on noncommutative spacetime
Zheng Ze Ma
We study the microcausality of free Dirac field on noncommutative spacetime. We calculate the vacuum and non-vacuum state expectation values for the Moyal commutator $[\barψ_α(x)\s…
Microcausality violation of scalar field on noncommutative spacetime with the time-space noncommutativity
Zheng Ze Ma
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 fie…
Commutators and propagators of Moyal star-products and microcausality for free scalar field on noncommutative spacetime
Zheng Ze Ma
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 commu…
Anticommutators and propagators of Moyal star-products for Dirac field on noncommutative spacetime
Zheng Ze Ma
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 prop…
Quantum motion equation and Poincare translation invariance of noncommutative field theory
Zheng Ze Ma
We study the Moyal commutators and their expectation values between vacuum states and non-vacuum states for noncommutative scalar field theory. For noncommutative scal…
