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…
