Contribution

It introduces a novel holographic description of $U(1)$ symmetries via non-BPS D-branes, expanding the understanding of gauge fields in string theory.

Findings

Consistent holographic description of $U(1)$ symmetries with non-BPS D-branes.

Validation of the proposal through multiple example cases.

Abstract

We propose a holographic description of the operators implementing $U(1)$ global symmetries that are dual to superstring gauge fields in terms of non-BPS D-branes. We check the consistency of our proposal in a number of examples.
