1. Primordial Black Holes from the QCD Axion / Ferrer, Francesc ; Masso, Eduard ; Panico, Giuliano ; Pujolas, Oriol ; et al
We propose a mechanism to generate primordial black holes (PBHs) that is independent of cosmological inflation and occurs slightly below the QCD phase transition. [...]

2. Holographic Phonons / Alberte, Lasma ; Ammon, Martin ; Jiménez-Alba, Amadeo ; Baggioli, Matteo ; et al
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 the elastic shear modulus according to elasticity theory. [...]

3. Black hole elasticity and gapped transverse phonons in holography / Alberte, Lasma ; Ammon, Martin ; Baggioli, Matteo ; Jiménez, Amadeo ; et al
We study the elastic response of planar black hole (BH) solutions in a simple class of holographic models with broken translational invariance. [...]

5. On effective holographic Mott insulators / Baggioli, Matteo ; Pujolàs, Oriol
We present a class of holographic models that behave effectively as prototypes of Mott insulators — materials where electron-electron interactions dominate transport phenomena. [...]

6. A natural origin for the LHCb anomalies / Megías, Eugenio ; Panico, Giuliano ; Pujolàs, Oriol ; Quirós, Mariano
The anomalies recently found by the LHCb collaboration in B -meson decays seem to point towards the existence of new physics coupled non-universally to muons and electrons. [...]

7. Viscosity bound violation in holographic solids and the viscoelastic response / Alberte, Lasma ; Baggioli, Matteo ; Pujolàs, Oriol
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 nonzero shear elastic modulus. [...]

9. Naturally light dilatons from nearly marginal deformations / Eugenio Megías ; Oriol Pujolàs
We discuss the presence of a light dilaton in CFTs deformed by a nearlymarginal operator O $$ \mathcal{O} $$ , in the holographic realizations consisting of confining RG flows that end on a soft wall. [...]
