Monopole Bubbling via String Theory

TL;DR

This paper introduces a string theory framework to describe monopole bubbling in supersymmetric gauge theories, linking moduli spaces of singular monopoles with brane configurations and T-duality.

Contribution

It provides a novel string theory description of 't Hooft defects and relates monopole moduli spaces to brane setups, offering a new approach to study monopole bubbling dynamics.

Findings

Moduli space of singular monopoles corresponds to supersymmetric ground states.

Kronheimer's correspondence is realized as T-duality in the brane setup.

Proposes a brane configuration to analyze monopole bubbling dynamics.

Abstract

In this paper, we propose a string theory description of generic 't Hooft defects in $\mathcal{N}=2$ $SU(N)$ supersymmetric gauge theories. We show that the space of supersymmetric ground states is given by the moduli space of singular monopoles and that in this setting, Kronheimer's correspondence is realized as T-duality. We conjecture that this brane configuration can be used to study the full dynamics of monopole bubbling.
