Precision holography of AdS${}_5$ bubbling geometries

Abstract

Holographic duality provides a microscopic interpretation of asymptotically Anti-de Sitter supergravity solutions. The dual states of the field theory give rise to expectation values of light operators. These expectation values correspond to coefficients in the asymptotic expansion of gauge-invariant combinations of supergravity fields. We consider the duality between type IIB theory on AdS${}_5\times$S${}^5$ and 4D $\mathcal{N}=4$ super Yang-Mills theory, focusing on the half-BPS sector. We clarify the structure of the precision holographic dictionary, making explicit the distinction between single-trace operators and single-particle operators, where the latter contain admixtures of multi-traces. We rewrite the holographic dictionary for half-BPS operators of dimension four in the single-particle basis. We then apply this dictionary to perform precision holographic studies of two different smooth supergravity solutions in the class derived by Lin, Lunin and Maldacena, that have been recently used to compute all-light four-point correlators by making extrapolations of heavy-light correlators.
