Experimental Tests of the Holographic Entropy Bound
Andreas Karch
Kovtun, Son and Starinets proposed a bound on the viscosity of any fluid in terms of its entropy density. The bound is saturated by maximally supersymmetric theories at strong coup…
Auto-localization in de-Sitter space
Andreas Karch
We point out that gravity on dS_n gives rise to a localized graviton on dS_{n-1}. This way one can derive a recursion relation for the entropy of dS spaces, which might have intere…
Construction of bosonic string theory on infinitely curved Anti-de Sitter space
Adam Clark, Andreas Karch, Pavel Kovtun +1
Free scalar field theory in the sector with a large number of particles can be interpreted as bosonic string theory on anti-de Sitter space of vanishing radius. Different ways of w…
Defect Conformal Field Theory and Locally Localized Gravity
Ofer Aharony, Oliver DeWolfe, Daniel Z. Freedman +1
Gravity may be "locally localized" over a wide range of length scales on a d-dimensional anti-de Sitter (AdS) brane living inside AdS_{d+1}. In this paper we examine this phenomeno…
