Vacua Landscape Attractor
Alvaro Nunez, Slava Solganik
The recent progress in the understanding of the landscape of string theory vacua hints that the hierarchy problem might be the problem of a super-selection rule. The attractor mech…
Ghost Constraints on Modified Gravity
Alvaro Nunez, Slava Solganik
We show that general infrared modifications of the Einstein-Hilbert action obtained by addition of curvature invariants are not viable. These modifications contain either ghosts or…
The content of f(R) gravity
Alvaro Nunez, Slava Solganik
We analyze the propagating degrees of freedom in gravity models where the scalar curvature in the action is replaced by a generic function of the curvature. That these gravi…
AdS/CFT correspondence, quasinormal modes, and thermal correlators in N=4 SYM
Alvaro Nunez, Andrei O. Starinets
We use the Lorentzian AdS/CFT prescription to find the poles of the retarded thermal Green's functions of SU(N) SYM theory in the limit of large N and large 't Hooft c…
