Overlaps for Matrix Product States of Arbitrary Bond Dimension in ABJM theory

arXiv:2207.06866 · doi:10.1016/j.physletb.2022.137428

Abstract

We find a closed formula for the overlap of Bethe eigenstates of an alternating spin chain, describing the scalar sector of ABJM theory, and matrix product states of any bond dimension representing 1/2 BPS co-dimension one domain walls in the field theory. One point functions of the defect CFTs involved, being directly expressible in terms of these overlaps, are hence completely determined.
