Higher derivative corrections to Lifshitz backgrounds

Abstract

We explore the effect of curvature-square corrections on Lifshitz solutions to the Einstein-Maxwell-dilaton system. After exhibiting the renormalized Lifshitz scaling solution to the system with parameterized R^2 corrections, we turn to a toy model with coupling g(\phi)C_{\mu\nu\rho\sigma}^2 and demonstrate that such a term can both stabilize the dilaton and resolve the Lifshitz horizon to AdS_2 x R^2. As an example, we construct numerical flows from AdS_4 in the UV to an intermediate Lifshitz region and then to AdS_2 x R^2 in the deep IR.
