Abstract We study the O(3) 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 ε-expansion. First, we extend by one order in perturbation theor

Abstract We present a dispersion relation for defect CFT that reconstructs two-point functions in the presence of a defect as an integral of a single discontinuity. The main virtue of this formula is that it streamlines explicit bootstrap calculation

Abstract We use the numerical bootstrap to study conformal line defects with O(2) global symmetry. Our results are very general and capture in particular conformal line defects originating from bulk CFTs with a continuous global symmetry, which can e

Abstract We use analytical bootstrap techniques to study supersymmetric monodromy defects in the critical Wess-Zumino model. In preparation for this result we first study two related systems which are interesting on their own: general monodromy defec

Abstract We study two-point functions of single-trace half-BPS operators in the presence of a supersymmetric Wilson line in N $$ \mathcal{N} $$ = 4 SYM. We use modern analytic bootstrap in the form of an inversion formula, that reconstructs the CFT d

Abstract Boundaries in three-dimensional N $$ \mathcal{N} $$ = 2 superconformal theories may preserve one half of the original bulk supersymmetry. There are two possibilities which are characterized by the chirality of the leftover supercharges. Depe

Abstract We apply the numerical conformal bootstrap to correlators of Coulomb and Higgs branch operators in 4d N $$ \mathcal{N} $$ = 2 superconformal theories. We start by revisiting previous results on single correlators of Coulomb branch operators.

Abstract We consider a non-supersymmetric domain-wall version of N $$ \mathcal{N} $$ = 4 SYM theory where five out of the six scalar fields have non-zero classical values on one side of a wall of codimension one. The classical fields have commutators

Abstract We study half-BPS line defects in N $$ \mathcal{N} $$ = 2 superconformal theories using the bootstrap approach. We concentrate on local excitations constrained to the defect, which means the system is a 1d defect CFT with osp(4∗ |2) symmet
