The time delay in strong gravitational lensing with Gauss-Bonnet correction
Jingyun Man, Hongbo Cheng
The time delay between two relativistic images in the strong gravitational lensing governed by Gauss-Bonnet gravity is studied. We derive and calculate the expression of time delay…
The greybody factor for scalar fields in the Schwarzschild spacetime with an global monopole
Jingyun Man, Hongbo Cheng
The greybody factor of massless scalar fields in the four-dimensional Schwarzschild spacetime involving an global monopole is derived. We show how the monopole parameter and…
The description of phase transition of Bardeen black hole in the Ehrenfest scheme
Jingyun Man, Hongbo Cheng
The phase transition of a Bardeen black hole is studied by considering Ehrenfest's equations. The thermodynamic variables such as entropy, potential and heat capacity are calculate…
The calculation of the thermodynamic quantities of the Bardeen black hole
Jingyun Man, Hongbo Cheng
In this work we research on the thermodynamical properties of the Bardeen black holes. We compute the series of new thermodynamic quantities such as local temperature, heat capacit…
The description of phase transition in a black hole with conformal anomaly in the Ehrenfest's scheme
Jingyun Man, Hongbo Cheng
We make use of the Ehrenfest's equation to explore the phase transition of a black hole with conformal anomaly. The first order phase transition is ruled out because no discontinui…
The thermodynamic quantities of a black hole with an global monopole
Jingyun Man, Hongbo Cheng
The thermodynamic quantities such as the local temperature, heat capacity, off-shell free energy and the stability of a black hole involving a global monopole within or outside the…
