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…
Slow relaxation and diffusion in holographic quantum critical phases
Richard A. Davison, Simon A. Gentle, Blaise Goutéraux
The dissipative dynamics of strongly interacting systems are often characterised by the timescale set by the inverse temperature . We show that near a class of…
Lifshitz entanglement entropy from holographic cMERA
Simon A. Gentle, Stefan Vandoren
We study entanglement entropy in free Lifshitz scalar field theories holographically by employing the metrics proposed by Nozaki, Ryu and Takayanagi in \cite{Nozaki:2012zj} obtaine…
On the reconstruction of Lifshitz spacetimes
Simon A. Gentle, Cynthia Keeler
We consider the reconstruction of a Lifshitz spacetime from three perspectives: differential entropy (or "hole-ography"), causal wedges and entanglement wedges. We find that not al…
Drude in D major
Tomas Andrade, Simon A. Gentle, Benjamin Withers
We study holographic momentum relaxation in the limit of a large number of spacetime dimensions D. For an axion model we find that momentum conservation is restored as D becomes la…
Holographic entanglement entropy of surface defects
Simon A. Gentle, Michael Gutperle, Chrysostomos Marasinou
We calculate the holographic entanglement entropy in type IIB supergravity solutions that are dual to half-BPS disorder-type surface defects in Super Yang-Mills theory…
