Transplanckian axion monodromy!?

<!--HTML-->We show that warped throats of the Klebanov-Strassler kind describe fully backreacted solutions of transplanckian axion monodromy. We show that the asymptotic Klebanov-Tseytlin solution features a 5d axion physically rolling through its dependence on an spatial coordinate, and traversing arbitrarily large geodesic distances in field space. We establish the description of the system in terms of an effective 5d theory for the axion, and verify its validity in transplanckian regimes.
