Abstract:

This talk is about the recent progress with black hole operators in the N=4 Super-Yang-Mills theory.

In this talk we will explain how to identify supercharge cohomologies of the weakly coupled SYM theory with finite-rank gauge groups, as holographic incarnation of the supersymmetric AdS black hole microstates.  Infinite towers of black hole (fortuitous) operators in the N=4 SYM with the smallest non-trivial gauge groups SU(2) and SU(3), and establish systematic arguments for their fortuity, i.e. they are not part of the supergraviton spectrum.

This talk will also demonstrate how one can extract gravitational features from the microscopic operators, namely that black holes may be dressed by graviton hair with large angular momenta or be wrapped by branes with large charges. The latter results in the brane-fused black hole operators, where symmetrized scalars are fused into the multi-trace structure of the core black hole operator to realize an infinite tower of dressed black hole operators with increasing charge.
