Comments on single trace and other current-current deformations
Gaston Giribet, Julio Oliva, Ricardo Stuardo
String theory on AdS with NS-NS fluxes admits a solvable irrelevant deformation which is close to the deformation of the dual CFT. This consists of deforming the…

Quasinormal modes and black hole hairs in AdS
Mariano Chernicoff, Gaston Giribet, Julio Oliva +1
Holography relates the quasinormal modes frequencies of AdS black holes to the pole structure of the dual field theory propagator. These modes thus provide the timescale for the ap…

Quadratic gravity and conformally coupled scalar fields
Nicolas Caceres, Jose Figueroa, Julio Oliva +2
We construct black hole solutions in four-dimensional quadratic gravity, supported by a scalar field conformally coupled to quadratic terms in the curvature. The conformal matter L…
