Supersymmetric D-branes in the D1-D5 background
Abstract
We construct supersymmetric D-brane probe solutions in the background of the 2-charge D1-D5 system on M, where M is either K3 or T4. We focus on `near-horizon bound states' that preserve supersymmetries of the near-horizon AdS3 x S3 x M geometry and are static with respect to the global time coordinate. We find a variety of half-BPS solutions that span an AdS2 subspace in AdS3, carry worldvolume flux and can wrap an S2 within S3 and/or supersymmetric cycles in M.
