Josef-Emanuel Seitz (Weizmann) “Stringy chaos and flat space fortuity”
Abstract: Black holes have large classical entropy, with the nature of the underlying microstates remaining a longstanding subject of interest. Among other expected properties, these microstates are expected to be chaotic. Recently, it has been conjectured that they are also`fortuitous’: they change erratically as one tunes the parameters of the theory. In this talk (based on work in progress with … Read More
Special String Theory: Zixia Wei (Harvard) “Monitoring a de Sitter universe through an anti-de Sitter window”
Abstract: Embedding a dS universe into an AdS spacetime is easy but identifying its CFT dual is nontrivial. In this talk, I focus on AdS3 gravity coupled to dS2 end-of-the-world branes, and identify its holographic dual to be a unitary holographic CFT2 with non-unitary conformal boundary conditions. These boundary conditions have complex g-functions and appear in conjugate pairs. The associated … Read More
