Masaki Shigemori -The Resolved Elliptic Genus and the D1-D5 CFT Room: Amphi Bloch, Salle Itzykson We introduce a new supersymmetry index, dubbed the resolved elliptic genus (REG), for the D1-D5 CFT on T^4. In a novel formulation of the CFT at the symmetric orbifold point based on the Schur-Weyl duality, we show how the REG can be naturally described and its protection is argued based on a selection rule derived from the action of the deformed supercharge. The REG is a one-parameter generalization of the standard index, the modified elliptic genus (MEG), and gives more fine-grained information about the structure of microstates than previously available. We demonstrate precise matching of the REG between supergravity and CFT below the black-hole threshold, where the MEG is trivial. Above the threshold, we uncover a decomposition of black-hole microstates into distinct sectors, invisible to the MEG. We expect both the new formalism and the REG to provide useful tools for studying the structure of black-hole microstates. In particular, we comment on their possible relevance to the fortuity program for understanding black-hole microstates within CFT.

Hao Geng - Recent Progress in Quantum Gravity Room: Amphi Bloch, Salle Itzykson I will review the recent progress in quantum gravity. The goal is to convey the follow three messages: 1. Most, if not all, of the problems in quantum gravity, i.e. black holes and closed universes, can be naturally understood in the Karch-Randall braneworld. 2. Karch-Randall braneworld has a clear string theory realization. 3. This calls for attention from string theory community to open the portal between string theory and quantum gravity.
