Description
Strongly correlated materials exhibit unconventional phases and mechanisms which cannot be explained within the standard condensed matter framework. Holographic theories provide a new and promising tool to shed light on these phenomena. I will motivate the duality between gravitational theories and real quantum materials using a phenomenological attitude. Incorporating momentum relaxation into these kind of theories has been a pressing issue which has been recently solved by mean of massive gravity. I will show how the graviton mass can provide an holographic dual for the Drude model. I will comment further about a simple generalization that exhibits an interaction-driven Metal-Insulator transition (MIT). The transition is triggered by the formation of polarons -- phonon-electron quasi-bound states that dominate the conductivities. Interestingly enough there are experimental hints which underline the role of polarons for MIT in manganite materials.
