Description

In this talk I will present a new holographic duality between a non-supersymmetric defect conformal field theory & its gravity dual. On the gravity side, the defect is realized by a D5 probe brane that wraps an S^2 subset of the S^5 and carries k units of flux through the S^2. The brane ends on an R^(1,1) subspace of the AdS5 boundary resulting to a codimension-2 defect. On the field theory side, the defect is described by a classical solution whose precise form we determine. We calculate the one-point functions of the energy-momentum tensor and of the chiral primary operators, both at strong and at weak coupling and in an appropriate limit we find compelling agreement between the two results.
