Microstate geometries and their (double) CFT description Seminar

Title: Microstate geometries and their (double) CFT description
Abstract: As is well known, the extremal 5D Reissner-Nordstrom black hole can be embedded in type IIB string theory by using the D-brane construction of Strominger and Vafa. Over the past years, several 1/8-BPS supergravity solutions have been constructed that can represent microstates for this black hole. From the D-brane construction, it is expected that each microstate solution should have two different CFT descriptions: one related to the near-horizon limit following from the AdS/CFT correspondence and another related to the asymptotic flat region in terms of the world-sheet CFT describing the D-branes. I will describe this double connection and present some new microstate geometries that should have a clear interpretation in both of these limits.
