Generalized holographic quantum criticality at finite density

Abstract

We show that the near-extremal solutions of Einstein-Maxwell-Dilaton theories, studied in [4], provide IR quantum critical geometries, by embedding classes of them in higher-dimensional AdS and Lifshitz solutions. This explains the scaling of their thermodynamic functions and their IR transport coefficients, the nature of their spectra, the Gubser bound, and regulates their singularities. We propose that these are the most general quantum critical IR asymptotics at finite density of EMD theories.
