Normal charge densities in quantum critical superfluids
Blaise Goutéraux, Eric Mefford
The normal density of a translation-invariant superfluid often vanishes at zero temperature, as is observed in superfluid Helium and conventional superconductors described by BCS t…
Gapless and gapped holographic phonons
Andrea Amoretti, Daniel Areán, Blaise Goutéraux +1
We study a holographic model where translations are both spontaneously and explicitly broken, leading to the presence of (pseudo)-phonons in the spectrum. The weak explicit breakin…
Diffusion and universal relaxation of holographic phonons
Andrea Amoretti, Daniel Areán, Blaise Goutéraux +1
In phases where translations are spontaneously broken, new gapless degrees of freedom appear in the low energy spectrum (the phonons). At long wavelengths, they couple to small flu…
Impact of irrelevant deformations on thermodynamics and transport in holographic quantum critical states
Richard A. Davison, Simon A. Gentle, Blaise Goutéraux
We study thermodynamic and transport observables of quantum critical states that arise in the infra-red limit of holographic renormalisation group flows. Although these observables…
Universal relaxation in a holographic metallic density wave phase
Andrea Amoretti, Daniel Areán, Blaise Goutéraux +1
In this work, we uncover a universal relaxation mechanism of pinned density waves, combining Gauge/Gravity duality and effective field theory techniques. Upon breaking translations…
Effective holographic theory of charge density waves
Andrea Amoretti, Daniel Areán, Blaise Goutéraux +1
We use Gauge/Gravity duality to write down an effective low energy holographic theory of charge density waves. We consider a simple gravity model which breaks translations spontane…
AdS/Ricci-flat correspondence and the Gregory-Laflamme instability
Marco M. Caldarelli, Joan Camps, Blaise Goutéraux +1
We show that for every asymptotically AdS solution compactified on a torus there is a corresponding Ricci-flat solution obtained by replacing the torus by a sphere, performing a We…
Black-Hole Solutions to Einstein's Equations in the Presence of Matter and Modifications of Gravitation in Extra Dimensions
B. Goutéraux
In this thesis, we wish to examine the black-hole solutions of modified gravity theories inspired by String Theory or Cosmology. Namely, these modifications will take the guise of…
