Abelian dualities and line defect indices for 3d gauge theories

Key Points

Matching pairs of line defect indices provide strong evidence for dualities in BPS line operators.
The findings lead to new duality maps for BPS line operators in N≥4 supersymmetric gauge theories.
These theories can be realized through brane configurations in Type IIB string theory, such as SQED and ABJM.
The implications of these dualities may enhance our understanding of supersymmetric gauge theories.

Abstract

A bstract We find matching pairs of the line defect indices for 3d supersymmetric Abelian gauge theories as strong evidence of dualities of the BPS line operators. They lead to novel duality maps of the BPS line operators for N 4 N ≥ 4 supersymmetric circular and linear quiver gauge theories which can be realized as brane configurations in Type IIB string theory, including SQED, ADHM and ABJM theories.
