Supercritical stability, transitions and (pseudo)tachyons
Ofer Aharony, Eva Silverstein
Highly supercritical strings (c much greater than 15) with a time-like linear dilaton provide a large class of solutions to string theory, in which closed string tachyon condensati…
Short distance properties of cascading gauge theories
Ofer Aharony, Alex Buchel, Amos Yarom
We study the short distance (large momentum) properties of correlation functions of cascading gauge theories by performing a tree-level computation in their dual gravitational back…
The CFT/AdS correspondence, massive gravitons and a connectivity index conjecture
Ofer Aharony, Adam B. Clark, Andreas Karch
We discuss the general question of which conformal field theories have dual descriptions in terms of quantum gravity theories on anti-de Sitter space. We analyze in detail the case…
Two loop partition function for large N pure Yang-Mills theory on a small three-sphere
Ofer Aharony, Joseph Marsano, Mark Van Raamsdonk
We give a direct path-integral calculation of the partition function for pure 3+1 dimensional U(N) Yang-Mills theory at large N on a small three-sphere, up to two-loop order in per…
A holographic model of deconfinement and chiral symmetry restoration
Ofer Aharony, Jacob Sonnenschein, Shimon Yankielowicz
We analyze the finite temperature behavior of the Sakai-Sugimoto model, which is a holographic dual of a theory which spontaneously breaks a U(N_f)_L x U(N_f)_R chiral flavor symme…
On the worldsheet theories of strings dual to free large N gauge theories
Ofer Aharony, Zohar Komargodski, Shlomo S. Razamat
We analyze in detail some properties of the worldsheet of the closed string theories suggested by Gopakumar to be dual to free large N SU(N) gauge theories (with adjoint matter fie…
