Massimo Porrati (NYU) “An Identity Crisis for Strings on AdS3 and its Resolution”
–
Abstract: Strings on the AdS3 Wess-Zumino model are solvable 2D CFT so they are known exactly in the worldsheet. Their target space Virasoro algebra is represented by vertex operators. The Virasoro central extension is represented by anidentity operator that should take the same value on all physical correlators, but it doesn’t. I show how to resolve this problem by properly … Read More

Daniel Harlow (Harvard) “Wormholes, Emergent Gauge Fields, and the Weak Gravity Conjecture”
–
Abstract: It has long been believed that the consistency of quantum gravity puts nontrivial constraints on electromagnetism that are invisible to semiclassical perturbation theory. In this talk I will present a paradox in AdS/CFT whose resolution seems to require three such constraints: the existence of charge states, the complete population of the charge lattice, and the weak gravity conjecture. This … Read More

Abstract: In this talk I will describe the observation of the binary black hole merger GW150914 from its gravitational wave signature. I will describe the methods applied in this discovery, the significance of the event, and properties of the binary system.
