N=2超引力中黑洞的熵

Entropy of Black Holes in N=2 Supergravity

Ayan Chatterjee

摘要:

利用孤立视界方法,构造了N=2纯超引力中四维渐近平坦极值黑洞的解空间。我们证明了黑洞力学定律。进一步,限制到常面积相空间,我们证明了球面视界存在U(1)Chern-Simons理论.量子化这个拓扑理论和计数状态的标准方法证实了熵确实与视界面积成正比。

英文摘要:

Using the techniques of isolated horizon formalism, we construct the space of solutions of asymptotically flat extremal black holes in N=2 pure supergravity in 4 dimensions. We prove the laws of black hole mechanics. Further, restricting to constant area phase space, we show that the spherical horizons admits a U(1) Chern- Simons theory. Standard way of quantizing this topological theory and counting states confirms that entropy is indeed proportional to the area of horizon.
