Query: A Scaling Limit for Line and Surface Defects   We study symmetry-breaking line defects in the Wilson-Fisher theory with
$O(2N+1)$ global symmetry near four dimensions and symmetry-preserving surface
defects in a cubic model with $O(2N)$ global symmetry near six dimensions. We
introduce a scaling limit inspired by the large charge expansion in Conformal
Field Theory. Using this, we compute the beta function for the defect coupling
which allows to identify the corresponding Defect Conformal Field Theories. We
also compute the correlation function of two parallel defects as well as
correlation functions of certain defect operators with large charge under the
surviving symmetry.
