Transport properties of spacetime-filling branes
Javier Tarrio
A model consisting of (d+1)-dimensional gravity coupled to spacetime filling charged branes is used to study the effects of backreaction. The charged black holes arising from this…
Holographic superconductivity in the large D expansion
Roberto Emparan, Kentaro Tanabe
We study holographic superconductivity by expanding the equations in the inverse of the number of spacetime dimensions D. We obtain an analytic expression for the critical temperat…
High energy bosons do not propagate
M. A. Kurkov, Fedele Lizzi, Dmitri Vassilevich
We discuss the propagation of bosons (scalars, gauge fields and gravitons) at high energy in the context of the spectral action. Using heat kernel techniques, we find that in the h…
Localization at Large N
J. G. Russo, K. Zarembo
We review how localization is used to probe holographic duality and, more generally, non-perturbative dynamics of four-dimensional N=2 supersymmetric gauge theories in the planar l…
Multiscale confining dynamics from holographic RG flows
Daniel Elander, Anton F. Faedo, Carlos Hoyos +2
We consider renormalization group flows between conformal field theories in five (six) dimensions with a string (M-theory) dual. By compactifying on a circle (torus) with appropria…
Longitudinal Coherence in a Holographic Model of p-Pb Collisions
Jorge Casalderrey-Solana, Michal P. Heller, David Mateos +1
As a model of the longitudinal structure in heavy ion collisions, we simulate gravitational shock wave collisions in anti-de Sitter space in which each shock is composed of multipl…
