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…
Entanglement entropy of Wilson surfaces from bubbling geometries in M-theory
Simon A. Gentle, Michael Gutperle, Chrysostomos Marasinou
We consider solutions of eleven-dimensional supergravity constructed in [1,2] that are half-BPS, locally asymptotic to and are the holographic dual of heavy Wilso…
Relaxed superconductors
Tomas Andrade, Simon A. Gentle
Momentum relaxation can be built into many holographic models without sacrificing homogeneity of the bulk solution. In this paper we study two such models: one in which translation…
Entanglement entropy of Wilson loops: Holography and matrix models
Simon A. Gentle, Michael Gutperle
A half-BPS circular Wilson loop in supersymmetric Yang-Mills theory in an arbitrary representation is described by a Gaussian matrix model with a particular…
Holographic entanglement and causal information in coherent states
Simon A. Gentle, Mukund Rangamani
Scalar solitons in global AdS4 are holographically dual to coherent states carrying a non-trivial condensate of a scalar operator. We study the holographic information content of t…
Collective Excitations of Holographic Quantum Liquids in a Magnetic Field
Daniel K. Brattan, Richard A. Davison, Simon A. Gentle +1
We use holography to study N=4 supersymmetric SU(Nc) Yang-Mills theory in the large-Nc and large-coupling limits coupled to a number Nf << Nc of (n+1)-dimensional massless supersym…
Superconducting instabilities of R-charged black branes
Simon A. Gentle, Benjamin Withers
We explore superconducting instabilities of black branes in SO(6) gauged supergravity at finite temperature and finite R-charge densities. We compute the critical temperatures for…
A soliton menagerie in AdS
Simon A. Gentle, Mukund Rangamani, Benjamin Withers
We explore the behaviour of charged scalar solitons in asymptotically global AdS4 spacetimes. This is motivated in part by attempting to identify under what circumstances such obje…
Shear channel correlators from hot charged black holes
Daniel K. Brattan, Simon A. Gentle
We compute numerically the full retarded Green's functions for conserved currents in the shear channel of a (2+1)-dimensional field theory at non-zero temperature and density. This…
