Phase Transition of the Higher Dimensional Charged Gauss-Bonnet Black Hole in de Sitter Spacetime
We study the phase transition of charged Gauss-Bonnet-de Sitter (GB-dS) black hole. For black holes in de Sitter spacetime, there is not only black hole horizon, but also cosmological horizon. The thermodynamic quantities on both horizons satisfy the first law of the black hole thermodynamics, resp...

| description | We study the phase transition of charged Gauss-Bonnet-de Sitter (GB-dS) black hole. For black
holes in de Sitter spacetime, there is not only black hole horizon, but also cosmological horizon.
The thermodynamic quantities on both horizons satisfy the first law of the black hole thermodynamics,
respectively; moreover, there are additional connections between them. Using the effective
temperature approach, we obtained the effective thermodynamic quantities of charged GB-dS black
hole. According to Ehrenfest classification, we calculate some response functions and plot their
figures, from which one can see that the spacetime undergoes a second-order phase transition at
the critical point. It is shown that the critical values of effective temperature and pressure decrease
with the increase of the value of GB parameter α. |
