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…
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…
Solid Holography and Massive Gravity
Lasma Alberte, Matteo Baggioli, Andrei Khmelnitsky +1
Momentum dissipation is an important ingredient in condensed matter physics that requires a translation breaking sector. In the bottom-up gauge/gravity duality, this implies that t…
Holographic Polarons, the Metal-Insulator Transition and Massive Gravity
Matteo Baggioli, Oriol Pujolas
Massive gravity is holographically dual to `realistic' materials with momentum relaxation. The dual graviton potential encodes the phonon dynamics and it allows for a much broader…
