bstract
A D3-D5 intersection gives rise to a defect CFT, wherein the rank of the gauge group jumps by
k
units across a domain wall. The one-point functions of local operators in this set-up map to overlaps between on-shell Bethe states in the underlying spin chain and a boundary state representing the D5 brane. Focussing on the
k
= 1 case, we extend the construction to gluonic and fermionic sectors, which was prohibitively difficult for
k >
1. As a byproduct, we test an all-loop proposal for the one-point functions in the
su
(2) sector at the half-wrapping order of perturbation theory. |
