Holographic dual of free field theory
Michael R. Douglas, Luca Mazzucato, Shlomo S. Razamat
We derive a holographic dual description of free quantum field theory in arbitrary dimensions, by reinterpreting the exact renormalization group, to obtain a higher spin gravity th…
On the Superconformal Index of N=1 IR Fixed Points: A Holographic Check
Abhijit Gadde, Leonardo Rastelli, Shlomo S. Razamat +1
We evaluate the superconformal index of the Y^{p,q} quiver gauge theories using Romeslberger's prescription. For the conifold quiver Y^{1,0} we find exact agreement at large N with…
On the critical condition in gravitational shock wave collision and heavy ion collisions
Shu Lin, Edward Shuryak
In this paper, we derived a critical condition for matter equilibration in heavy ion collisions using a holographic approach. A gravitational shock waves with infinite transverse e…
Improved AdS/QCD Model with Matter
Alexander Stoffers, Ismail Zahed
We study an improved AdS/QCD model at finite temperature and chemical potential. An Ansatz for the beta-function for the boundary theory allows for the derivation of a charged dila…
Off-shell N=(4,4) supersymmetry for new (2,2) vector multiplets
M. Goteman, U. Lindstrom, M. Rocek +1
We discuss the conditions for extra supersymmetry of the N=(2,2) supersymmetric vector multiplets described in arXiv:0705.3201 [hep-th] and in arXiv:0808.1535 [hep-th]. We find (4,…
Energy Flux Positivity and Unitarity in CFTs
Manuela Kulaxizi, Andrei Parnachev
We show that in most conformal field theories the condition of the energy flux positivity, proposed by Hofman and Maldacena, is equivalent to the absence of ghosts. At finite tempe…
