Stability of a black hole under the deformation of an extended periodic potential
Shi-Jie Ma, Run-Qiu Yang
It has been shown that the spectrum of black hole quasi-normal modes is extremely sensitive to localized deformations of the geometry away from the potential peak. The deformation…
Near-Horizon Deformation of Metric and the Black Hole Instability
Shi-Jie Ma, Zhan-Feng Mai, Run-Qiu Yang
Recent time-domain analyses suggest that black hole stability may be sensitive to localized near-horizon geometric deformations, while the underlying spectral mechanism remains unc…
Quasinormal modes and greybody factor of charged black hole in non-commutative geometry
Shi-Jie Ma, Rui-Bo Wang, Tian-Chi Ma +3
In this article, the quasinormal modes and greybody factor of charged black hole in non-commutative geometry are studied. Under the assumption of a uniformly distributed charge wit…
Estimating the strength of Lorentzian distribution in non-commutative geometry by solar system tests
Rui-Bo Wang, Shi-Jie Ma, Jian-Bo Deng +1
In this paper, we study four classical tests of Schwarzschild space-time with Lorentzian distribution in non-commutative geometry. We performed detailed calculations of the first-o…
Thermodynamic properties and Joule-Thomson expansion of AdS black hole with Gaussian distribution in non-commutative geometry
Rui-Bo Wang, Lei You, Shi-Jie Ma +2
The thermodynamics and Joule-Thomson expansion of anti-de Sitter black hole (AdS BH) with Gaussian distribution in non-commutative geometry is systematically studied. The metric of…
Thermodynamics of Schwarzschild-AdS black hole in non-commutative geometry
Rui-Bo Wang, Shi-Jie Ma, Lei You +2
In this paper, we study the thermodynamics of Schwarzschild-anti-de Sitter black holes within the framework of non-commutative geometry. By solving the Einstein's equations, we der…
