报告摘要：

The near horizon limit of extremal black holes displayed the AdS2 geometry, whose entropy can be understood by the famous Kerr/CFT correspondence. In specific AdS_5 black holes, it is known the near horizon geometry can be lifted to AdS3. This is known as the Extremal vanishing horizon limit, with S=k T scaling. And the entropy of AdS3 can be shown to be reduced from the superconformal indices of N=4 SYM, indicating a step towards proving Kerr/CFT correspondence from AdS/CFT.

Higher dimensional black holes would allow more fruitful parameter spaces. In this talk I will discuss the near EVH limits of AdS_6 and AdS_7 black holes. The scalings between entropy and temperature will be S=k T^2 and S=k T^3. We will show the geometry is not of AdS type but Einstein-Maxwell-Maxwell-Dilaton black holes. These geometry thus generalize the AdS_2 in the near horizon limits, and opens a possibility to understand microscopic states of EMMD black holes in (D-2) dimensions, from its AdS_D black hole embeddings.
