We find exact, analytic solutions of the holographic AC conductivity at arbitrary frequency ω and temperature T, in contrast to previous works where the AC conductivity was analytically obtained usually at small ω and T. These solutions enable us to study the analyticity properties of the current-current correlator G(ω) in detail. The first system we study is the AdS5 planar black hole with momentum dissipation, whose extremal limit has an AdS2 factor. Then we study AdS4 and AdS5 Einstein-dilaton systems whose special cases are maximal gauged supergravities. The solutions show how the poles move and how branch cuts emerge as the temperature varies. As a byproduct, we obtain an R-current correlator in =4 super-Yang-Mills theory on a sphere at finite temperature in the large N and strong coupling limit.
