Energy-momentum non-conservation on noncommutative spacetime and the existence of infinite spacetime dimension
Zheng Ze Ma
From the constructions of the quantum spacetime, a four dimensional quantized spacetime can be embedded in a five dimensional continuous spacetime. Thus to observe from the five di…
Hawking Radiation of Black p-Branes from Gravitational Anomaly
Zheng Ze Ma
We investigate the Hawking radiation of black -branes of superstring theories using the method of anomaly cancelation, specially, we use the method of [S. Iso, H. Umetsu and F.…
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…
