Résumé :
We examine the black brane solutions of Einstein-Maxwell-Dilaton theories with a single Liouville exponential potential and classify them, commenting on their unusual asymptotic properties: two classes of integrable solutions with mass and charge are found in particular cases, while in the generic case, only the near-extremal solution with mass and fixed charge can be obtained. Then, we move on and study their thermodynamics: we find close resemblance to the usual, non-dilatonic cases. We pursue by computing their transport coefficients, looking for strange metals characteristics in the AC conductivity. Finally, we revisit the solutions and connect them through Kaluza-Klein oxidation to well-known black hole and q-brane solutions in higher dimensions, thus allowing to interpret the above properties.
