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…
Holographic collisions in confining theories
Vitor Cardoso, Roberto Emparan, David Mateos +2
We study the gravitational dual of a high-energy collision in a confining gauge theory. We consider a linearized approach in which two point particles traveling in an AdS-soliton b…
Black String Flow
Roberto Emparan, Marina Martinez
We give an exact description of the steady flow of a black string into a planar horizon. The event horizon is out of equilibrium and provides a simple, exact instance of a `flowing…
Large D gravity and low D strings
Roberto Emparan, Daniel Grumiller, Kentaro Tanabe
We point out that in the limit of large number of dimensions a wide class of non-extremal neutral black holes has a universal near horizon limit. The limiting geometry is the two-d…
Effective hydrodynamics of black D3-branes
Roberto Emparan, Veronika E Hubeny, Mukund Rangamani
The long-wavelength effective field theory of world-volume fluctuations of black D3-branes is shown to be a hydrodynamical system to leading order in a gradient expansion. We study…
The large D limit of General Relativity
Roberto Emparan, Ryotaku Suzuki, Kentaro Tanabe
General Relativity simplifies dramatically in the limit that the number of spacetime dimensions D is infinite: it reduces to a theory of non-interacting particles, of finite radius…
