Cusped Defects: Cusp Operator Expansion, Conformal Properties and Bootstrap Applications

Lorenzo Bianchi, Andrea Cavaglià, A. David Gutiérrez +2

We analyze general properties of cusped defect lines embedded in generic conformal field theories (CFTs). We prove that suitably defined cusp scaling operators transform like prima…

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…

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…

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…

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…

Analytic bootstrap for magnetic impurities

Lorenzo Bianchi, Davide Bonomi, Elia de Sabbata +1

We study the critical model and the free theory of a scalar triplet in the presence of a magnetic impurity. We use analytic bootstrap techniques to extract results in the $\…
