On Effective Holographic Mott Insulators
Matteo Baggioli, Oriol Pujolas
We present a class of holographic models that behave effectively as prototypes of Mott insulators, materials where electron-electron interactions dominate transport phenomena. The…

On holographic disorder-driven metal-insulator transitions
Matteo Baggioli, Oriol Pujolas
We give a minimal holographic model of a disorder-driven metal-insulator transition. It consists in a CFT with a charge sector and a translation-breaking sector that interact in th…

Viscosity bound violation in holographic solids and the viscoelastic response
Lasma Alberte, Matteo Baggioli, Oriol Pujolas
We argue that the Kovtun--Son--Starinets (KSS) lower bound on the viscosity to entropy density ratio holds in fluid systems but is violated in solid materials with a non-zero shear…
