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 $\…

Analytic bootstrap for the localized magnetic field
Lorenzo Bianchi, Davide Bonomi, Elia de Sabbata
We study the two-point function of local operators in the critical O(N) model in the presence of a magnetic field localized on a line. We use a recently developed conformal dispers…

Conformal dispersion relations for defects and boundaries
Lorenzo Bianchi, Davide Bonomi
We derive a dispersion relation for two-point correlation functions in defect conformal field theories. The correlator is expressed as an integral over a (single) discontinuity tha…
