Particle Acceleration on the Background of the Kerr-Taub-NUT Spacetime
Changqing Liu, Songbai Chen, Chikun Ding +1
We study the collision of two particles with the different rest masses moving in the equatorial plane of a Kerr-Taub-NUT spacetime and get the center-of-mass (CM) energy for the pa…
Strong gravitational lensing in a noncommutative black-hole spacetime
Chikun Ding, Shuai Kang, Chang-Yong Chen +2
Noncommutative geometry may be a starting point to a quantum gravity. We study the influence of the spacetime noncommutative parameter on the strong field gravitational lensing in…
Extension of non-minimal derivative coupling theory and Hawking radiation in black-hole spacetime
Chikun Ding, Changqing Liu, Jiliang Jing +1
We study the greybody factor and Hawking radiation with a non-minimal derivative coupling between the scalar field and the curvature in the background of the slowly rotating Kerr-N…
Analytical expressions for greybody factor and dynamic evolution for scalar field in Hořava-Lifshitz black hole
Chikun Ding, Songbai Chen, Jiliang Jing
We investigate the propagation and evolution for a massless scalar field in the background of Hořava-Lifshitz black hole with the condition of detailed balance. We fortunat…
Deformation of contour and Hawking temperature
Chikun Ding, Jiliang Jing
It was found that, in an isotropic coordinate system, the tunneling approach brings a factor of 1/2 for the Hawking temperature of a Schwarzschild black hole. In this paper, we add…
