题目：Acoustic black holes: a holographic perspective".

讲座摘要:
The acoustic black hole was originally proposed as an analogous model of the real black hole. Although it can mimic some important features of the real black hole such as the horizon and the Hawking radiation. The underlying dynamics of the acoustic black hole and those of the real black hole are rather different, thus the observing of the Hawking-like radiation of the former doesn't mean the detecting of the Hawking radiation of the latter. However, in this talk, We will show that, when the gauge/gravity duality, especially the fluid/gravity duality is taken into account, the acoustic black hole is not merely an analogous black hole system, it indeed can be used to describe specific fluctuations of
the bulk black hole in the hydrodynamic limit in the viewpoint of the gauge/gravity duality.

题目：Pair Production in Kerr-Newman Black Holes
时间地点：7月22日 15：00 理学A楼 一楼会议室
报告人：Chiang-Mei Chen
讲座摘要：
In this talk, I will present, in details, the pair production,including the Schwinger mechanism and the Hawking thermal radiation, of charged scalar particles from the near horizon region of a (near) extremal Reissner-Nordstr"om black hole. The absorption cross section can be exactly computed. A holographic description dual to the pair production is also briefly discussed. In addition, the preliminary results of the generalization to the Kerr-Newman black holes will be reported.
