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…
