In boundary conformal field theories, global symmetries can be broken by boundary
conditions, generating a homogeneous conformal manifold. We investigate these …

A bstract 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 …

A bstract In this paper we initiate the study of correlation functions of a single trace operator
and a circular supersymmetric Wilson loop in ABJM theory. The single trace operator is in …

A bstract We study and compute supersymmetric observables for line defects in 3d\(\mathcal
{N}\)≥ 4 theories. Our setup is a novel supersymmetric configuration involving line operators …

A bstract We continue our study of renormalization group (RG) flows on Wilson loop defects
in ABJM theory, which we have initiated in arXiv: 2211.16501. We generalize that analysis …

A bstract We use the numerical conformal bootstrap to study boundary quantum
electrodynamics, the theory of a four dimensional photon in a half space coupled to charged …

In this thesis, we consider two approaches to the study of correlation functions in
onedimensional defect Conformal Field Theories (dCFT 1), in particular those defined by 1/2 …

In ABJM theory, enriched RG flows between circular 1/6 BPS bosonic and 1/2 BPS fermionic
Wilson loops have been introduced in L. Castiglioni et al.[L. Castiglioni, S. Penati, M. Tenser …

Scalar-fermion models, such as the Gross-Neveu-Yukawa model, admit natural $1 d $
defects given by the exponential of a scalar field integrated along a straight line. In $4 …

A bstract In this paper we complete the exploration of connected components of the space of
BPS Wilson loops in three-dimensional\(\mathcal {N}\)= 4 Chern-Simons-matter theory on S …
