The Effects of Near-AdS Backreaction on Matter Fields
Alejandra Castro, Jildou Hollander, Pedro J. Martinez +1
We quantify how the two-point function of a real scalar field is affected by the distortion caused by deforming AdS to a near-AdS background. At tree-level, the backreactio…

Revisiting Extremal Couplings in AdS/CFT
Alejandra Castro, Pedro J. Martinez
We consider an effective theory of massive scalar fields on a fixed AdS background with a cubic extremal interaction among them. A bulk coupling is called extremal whenever…
