We study the low-energy limit of Wilson lines (charged impurities) in conformal gauge
theories in 2+ 1 and 3+ 1 dimensions. As a function of the representation of the Wilson line …

Defects in conformal field theory (CFT) are of significant theoretical and experimental
importance. The presence of defects theoretically enriches the structure of the CFT, but at …

A bstract Topological/perfectly-transmissive defects play a fundamental role in the analysis
of the symmetries of two dimensional conformal field theories (CFTs). In the present work …

A bstract We study the rich dynamics resulting from introducing static charged particles
(Wilson lines) in 2+ 1 and 3+ 1 dimensional gauge theories. Depending on the charges of …

A bstract We present a systematic method for the derivation of a relation which connects the
correlation function of operators on the straight Maldacena-Wilson line with the integrability …

A bstract 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 …

A bstract A general analysis of line defect renormalisation group (RG) flows in the ε
expansion below d= 4 dimensions is undertaken. The defect beta function for general scalar …

A bstract We combine perturbation theory with analytic and numerical bootstrap techniques
to study the critical point of the long-range Ising (LRI) model in two and three dimensions …

A bstract We employ the axiomatic framework of Rychkov and Tan to investigate the critical
O (N) vector model with a line defect in (4− ϵ) dimensions. We assume the fixed point is …

Defects are common in physical systems with boundaries, impurities or extensive
measurements. The interaction between bulk and defect can lead to rich physical …
