Abstract

The scaling of the AC conductivity in quantum critical holographic theories at finite density, finite temperature, and in the presence of momentum dissipation is considered. It is shown that there is generically an intermediate window of frequencies in which the IR scaling of the AC conductivity is clearly visible.
