Double-trace operators in orbifold QFT
There are two different types of the action of the orbifold group Γ on S5 -with and without fixed points. According to [2] in the first case the twisted sector of string theory in such a geometry contains a tachyon, and therefore the geometry AdS5 × S5/Γ is not stable and is not a valid description of QFT. So, we conclude that the orbifolds with fixed point are not conformal at strong coupling....

متن کامل“Double-trace” Deformations, Boundary Conditions and Spacetime Singularities
Double-trace deformations of the AdS/CFT duality result in a new perturbation expansion for string theory, based on a non-local worldsheet. We discuss some aspects of the deformation in the low energy gravity approximation, where it appears as a change in the boundary condition of fields. We relate unique features of the boundary of AdS to the worldsheet becoming non-local, and conjecture that ...
متن کاملDouble Trace Deformations, Infinite Extra Dimensions, and Supersymmetry Breaking
It was recently shown how to break supersymmetry in certain AdS3 spaces, without destabilizing the background, by using a “double trace” deformation which localizes on the boundary of space-time. By viewing spatial sections of AdS3 as a compactification space, one can convert this into a SUSY breaking mechanism which exists uniformly throughout a large 3+1 dimensional space-time, without genera...
متن کاملThe electric double layer structure around charged spherical interfaces.
We derive a formally simple approximate analytical solution to the Poisson-Boltzmann equation for the spherical system via a geometric mapping. Its regime of applicability in the parameter space of the spherical radius and the surface potential is determined, and its superiority over the linearized solution is demonstrated.
