Surface defects in holographic 5d SCFTs

We use holography to study codimension-2 surface defects in 5d SCFTs engineered by (p, q) 5-brane webs. The three-dimensional defects are realized by D3-branes ending on the brane web. We identify the holographic representation of the defects in Type IIB AdS(6) solutions as probe D3-branes, and study conformal and non-conformal defects which, respectively, preserve one half and one quarter of the supersymmetry. For a sample of 5d SCFTs, including the T-N theories, we provide explicit solutions for conformal and non-conformal defects. For the conformal defects we obtain their contribution to the free energy on S-5.

Automated summary

In this study, holography is used to investigate codimension-2 surface defects in 5d SCFTs engineered by (p, q) 5-brane webs. The three-dimensional defects are realized by D3-branes ending on the brane web, with their holographic representation in Type IIB AdS(6) solutions as probe D3-branes. The study focuses on conformal and non-conformal defects preserving different fractions of supersymmetry, providing explicit solutions for a sample of 5d SCFTs, including the T-N theories.
