Conformal defects and Goldstone bosons in Anti-de Sitter space
Lorenzo Bianchi, Elia de Sabbata, Marco Meineri
We study local quantum field theories in Anti-de Sitter (AdS) space, with boundary conditions that break some of the bulk isometries. Specifically, we focus on conformal defects an…
Lightcone Bootstrap for Multipoint Defect Correlators
Lorenzo Bianchi, Andrea Mattiello, Lorenzo Quintavalle
We initiate the lightcone bootstrap analysis of multipoint correlators in a defect conformal field theory. The setup we consider is the three-point function of two bulk and one def…
An unusual BPS equation
Constantin Bachas, Lorenzo Bianchi, Zhongwu Chen
We prove a conjectured relation between the energy-momentum and the displacement norm of superconformal defects. The proof completes earlier results, and shows that supersymmetry i…
The entropy of radiation for local quenches in higher dimensions
Lorenzo Bianchi, Andrea Mattiello, Jacopo Sisti
We investigate the real time dynamics of the radiation produced by a local quench in a -dimensional conformal field theory (CFT) with . Using the interpretation of the high…
Defects in the long-range O(N) model
Lorenzo Bianchi, Leonardo S. Cardinale, Elia de Sabbata
We initiate the study of extended excitations in the long-range O(N) model. We focus on line and surface defects and we discuss the challenges of a naive generalization of the simp…
