Hawking Radiation, Information Paradox and Emission from the D1-D5 System
I will present an introduction to the Penrose process, superradiance and Hawking radiation. I will then explain the information paradox and how robust it is. The fuzzball proposal will then be introduced with the two-charge systems being reviewed. A discussion of emission calculations for D1-D5-P black holes and for certain non-extremal fuzzballs from both the gravity and CFT perspectives will be presented. I will show how seemingly different emission processes in gravity, namely, Hawking radiation and superradiance from D1-D5-P black holes, and ergoregion instability of certain non-extremal fuzzballs, are only different manifestations of the same phenomenon in the CFT.
