Bootstrapping line defects in AdS/CFT
Gabriel Bliard, Diego H. Correa, Martín Lagares +1
We study correlators of insertions along 1/2 BPS line defects in the holographic dual to type IIB string theory in with mixed Ramond-Ramond and Neveu…
On multipoint Ward identities for superconformal line defects
Gabriel Bliard
Superconformal Ward identities are revisited in the context of superconformal line defects. Multipoint correlators of topological operators inserted on superconformal lines are stu…
Perturbative and non-perturbative analysis of defect correlators in AdS/CFT
Gabriel J. S. Bliard
In this thesis, we consider two approaches to the study of correlation functions in one-dimensional defect Conformal Field Theories (dCFT), in particular those defined by 1/2-B…
Holography on the lattice: the string worldsheet perspective
Gabriel Bliard, Ilaria Costa, Valentina Forini
We review the study, on the lattice, of the Green-Schwarz gauge-fixed string action describing worldsheet fluctuations about the minimal surface holographically dual to the null cu…
Notes on -point Witten diagrams in AdS
Gabriel Bliard
Witten diagrams provide a perturbative framework for calculations in Anti-de-Sitter space, and play an essential role in a variety of holographic computations. In the case of this…
Lattice perturbation theory for the null cusp string
Gabriel Bliard, Ilaria Costa, Valentina Forini +1
We reconsider the problem of discretising the worldsheet for the gauge-fixed Green-Schwarz superstring on a null cusp background, and present a setup which fully preserves its glob…
Mellin amplitudes for 1 CFT
Lorenzo Bianchi, Gabriel Bliard, Valentina Forini +1
We define a Mellin amplitude for CFT four-point functions. Its analytical properties are inferred from physical requirements on the correlator. We discuss the analytic continua…
Analytic bootstrap and Witten diagrams for the ABJM Wilson line as defect CFT
Lorenzo Bianchi, Gabriel Bliard, Valentina Forini +2
We study local operator insertions on 1/2-BPS line defects in ABJM theory. Specifically, we consider a class of four-point correlators in the CFT with SU superconform…
