Words to describe a black hole
Ying-Hsuan Lin, Harvard University,

Note: special time. The talk is in 469 Lauritsen

We revamp the constructive enumeration of 1/16-BPS states in the maximally supersymmetric Yang-Mills in four-dimensions, and search for ones that are not of multi-graviton form. A handful of such states are found for gauge group SU(2) at relatively high energies, resolving a decade-old enigma. Along the way, we clarify various subtleties in the literature, and prove a non-renormalization theorem about the exactness of the cohomological enumeration in perturbation theory. We point out a giant-graviton-like feature in our results, and envision that a deep analysis of our data will elucidate fundamental properties of black hole microstates.
