Abstract

The string theory approach to quantum gravity forms the context for our discussion of two interrelated themes: microscopic string modelling of black holes, and AdS/CFT holography.

A 2009 result of S.Mathur showed that the black hole information paradox cannot be resolved via semiclassical perturbation theory. Starting from the microscopic SCFT of the prototype D1-D5-brane system in a top-down approach, we use conformal perturbation theory to explore aspects of deforming towards the classical black hole geometry.

Our second theme recruits a more bottom-up motivation to explore holographic setups with increasing amounts of broken symmetry. We discuss modelling disorder holographically for the charged case, using perturbation theory in disorder strength to construct solutions including gravitational backreaction, and find the conductivity.
