五维中性Gauss-Bonnet AdS黑洞有趣的微观结构

Intriguing microstructures of five-dimensional neutral Gauss-Bonnet AdS black hole

Shao-Wen Wei, Yu-Xiao Liu

摘要:

本文研究了五维中性Gauss-Bonnet AdS黑洞的相结构,并在扩展相空间中构造了Ruppeiner几何.通过计算Ruppeiner几何的标量曲率并结合相变,我们证明了吸引相互作用在黑洞系统的微观结构中占主导地位。更重要的是,有一个有趣的性质,归一化标量曲率有相同的表达式饱和的小和大黑洞曲线。这意味着虽然小-大黑洞相变前后微观结构不同,但微观组分之间的相互作用保持不变。这些结果对进一步理解修正引力下AdS黑洞的微观结构具有重要的参考价值。

英文摘要:

In this paper, we analytically study the phase structure and construct the Ruppeiner geometry in the extended phase space for the five-dimensional neutral Gauss-Bonnet AdS black hole. Through calculating the scalar curvature of the Ruppeiner geometry and combining the phase transition, we show that the attractive interaction is dominant in the microstructure of the black hole system. More significantly, there is an intriguing property that the normalized scalar curvature has the same expression for the saturated small and large black hole curves. This implies that although the microstructure is different before and after the small-large black hole phase transition, the interaction between the microscopic constituents keeps unchanged. These results are quite valuable on further understanding the microstructure of the AdS black hole in modified gravity.
