报告摘要:
Hawking’s seminal work in 1970s showed that black holes obey a set of rules, which are similar to the classical thermodynamics. In particular, the entropy of a black hole is proportional to the area of its horizon. A natural question is whether we can find the entropy by directly counting the microstates of a black hole, like statistical mechanics founded by Boltzmann. This problem for AdS_3 BPS black holes was solved by Strominger and Vafa in 1996. However, for the AdS_5 BPS black holes the problem had remained open for many years. Recently, several different groups successfully reproduce the entropies of AdS_5 BPS black holes from the microscopic side using supersymmetric localization, perturbative matrix model and superconformal index with complex chemical potentials. Inspired by this breakthrough, we can also study BPS black holes in other dimensions, e.g. the AdS_4 case. More interestingly, we find that the microstate counting works also for AdS_5 near-BPS black holes without supersymmetry. In this talk I will discuss various aspects of these new developments. This talk is based on the paper 1907.02505 and some work in progress.
