Transdimensional Defects
Elia de Sabbata, Nadav Drukker, Andreas Stergiou
This note introduces a novel paradigm for conformal defects with continuously adjustable dimensions. Just as the standard expansion interpolates between integer space…

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 $\…
