论文摘要
我们通过引入一个新的订单参数（由于非线性耦合电磁场而引起的磁性电荷的电势）来研究常规Hayward-Ads黑洞的相变。我们使用Landau连续相变理论来讨论范德华，例如黑洞的关键现象。作为大型黑洞和小黑洞之间的广泛解释为黑洞相变，作为高电位相位和低电位相之间的跃迁。使用Ruppeiner几何形状探测该相变的基础微观结构。通过研究Ruppeiner标量曲率的行为，我们发现黑洞的带电和未充电的（有效）分子具有类似于费米和玻色子气体的不同微结构。
We study the phase transition of a regular Hayward-AdS black hole by introducing a new order parameter, the potential conjugate to the magnetic charge due to the non-linearly coupled electromagnetic field. We use Landau continuous phase transition theory to discuss the van der Waals like critical phenomena of the black hole. The popular interpretation of the AdS black hole phase transition as between a large and a small black hole is reinterpreted as the transition between a high potential phase and a low potential phase. The underlying microstructure for this phase transition is probed using the Ruppeiner geometry. By investigating the behaviour of the Ruppeiner scalar curvature, we find that the charged and uncharged (effective) molecules of the black hole have distinct microstructures analogous to fermion and boson gas.
