Holographic Lifshitz flows
Matteo Baggioli, Oriol Pujolas, Xin-Meng Wu
Without Lorentz symmetry, generic fixed points of the renormalization group (RG) are labelled by their dynamical (or `Lifshitz') exponent . Hence, a rich variety of possible RG…
Black Rubber and the Non-linear Elastic Response of Scale Invariant Solids
Matteo Baggioli, Victor Cancer Castillo, Oriol Pujolas
We discuss the nonlinear elastic response in scale invariant solids. Following previous work, we split the analysis into two basic options: according to whether scale invariance (S…
Elasticity bounds from Effective Field Theory
Lasma Alberte, Matteo Baggioli, Victor Cancer Castillo +1
Phonons in solid materials can be understood as the Goldstone bosons of the spontaneously broken spacetime symmetries. As such their low energy dynamics are greatly constrained and…
Holographic Phonons
Lasma Alberte, Martin Ammon, Matteo Baggioli +2
We present a class of holographic massive gravity models that realize a spontaneous breaking of translational symmetry - they exhibit transverse phonon modes whose speed relates to…
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…
