报告摘要:

Recent progress in applications of AdS/CFT correspondence allows us to count the microstates of supersymmetric extremal AdS black holes, both from the boundary superconformal field theories and from near-horizon 2d conformal field theories. Various different approaches can lead to the same result of BPS black hole entropy. In fact, similar ideas and approaches can be applied to near-extremal rotating AdS black holes with small temperatures. This makes it possible to set up a microscopic description of Hawking radiation for near-extremal rotating AdS black holes, which generalizes the work by Callan and Maldacena for asymptotically flat black holes. Moreover, by considering a wave equation in a rotating AdS black hole background, we can compute the corresponding shear viscosity, which extends and naturally violates the (shear viscosity)-to-(entropy density) bound 1/(4 \pi) found by Kovtun, Son and Starinets. In this talk we will discuss in detail the aspects mentioned above. This talk is based on my recent papers with collaborators 2003.02770, 2005.10251, 2009.12370 and 2012.02797.
