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…
Quantum critical scaling and holographic bound for transport coefficients near Lifshitz points
Gian Andrea Inkof, Joachim M. C. Kuppers, Julia M. Link +2
The transport behavior of strongly anisotropic systems is significantly richer compared to isotropic ones. The most dramatic spatial anisotropy at a critical point occurs at a Lifs…
Theory of the collective magnetophonon resonance and melting of the field-induced Wigner solid
Luca V. Delacrétaz, Blaise Goutéraux, Sean A. Hartnoll +1
Electron solid phases of matter are revealed by characteristic vibrational resonances. Sufficiently large magnetic fields can overcome the effects of disorder, leading to a weakly…
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…
Theory of hydrodynamic transport in fluctuating electronic charge density wave states
Luca V. Delacrétaz, Blaise Goutéraux, Sean A. Hartnoll +1
We describe the collective hydrodynamic motion of an incommensurate charge density wave state in a clean electronic system. Our description simultaneously incorporates the effects…
Bad Metals from Fluctuating Density Waves
Luca V. Delacrétaz, Blaise Goutéraux, Sean A. Hartnoll +1
Bad metals have a large resistivity without being strongly disordered. In many bad metals the Drude peak moves away from zero frequency as the resistivity becomes large at increasi…
Hydrodynamic theory of quantum fluctuating superconductivity
Richard A. Davison, Luca V. Delacrétaz, Blaise Goutéraux +1
A hydrodynamic theory of transport in quantum mechanically phase-disordered superconductors is possible when supercurrent relaxation can be treated as a slow process. We obtain gen…
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…
Einstein-Maxwell-Dilaton theories with a Liouville potential
Christos Charmousis, Blaise Goutéraux, Jiro Soda
We find and analyse solutions of Einstein's equations in arbitrary d dimensions and in the presence of a scalar field with a Liouville potential coupled to a Maxwell field. We cons…
