Distinguishing Between Dark Matter-Black Hole Systems and Naked Singularities via Quasi-Periodic Oscillations
Zheng Ma, Meirong Tang, Zhaoyi Xu
Quasi-Periodic Oscillations (QPOs) are an important phenomenon commonly observed in the X-ray radiation of black holes and neutron stars, closely related to the dynamics of accreti…
Hawking temperature of Kerr-Newman-AdS black hole from tunneling
Zheng Ze Ma
Using the null-geodesic tunneling method of Parikh and Wilczek, we derive the Hawking temperature of a general four-dimensional rotating black hole. In order to eliminate the motio…
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…
