Strings from large charged fields

TL;DR

This paper reviews instances where non-abelian gauge theories at low energies exhibit behaviors akin to extended objects such as strings or branes, highlighting the duality between gauge theories and string-like descriptions.

Contribution

It provides a comparative analysis of specific examples where gauge theories mimic string or brane dynamics, emphasizing the conditions and limits of such effective descriptions.

Findings

Non-abelian gauge theories can exhibit string-like behavior in certain limits.

Examples demonstrate the duality between gauge theories and extended objects.

The paper clarifies the conditions under which gauge theories resemble string or brane dynamics.

Abstract

It has been known long time ago that the low energy dynamics of open-strings is described by non-abelian gauge theories in the same way that the low energy effective description of closed strings is governed by Einstein's gravity. In this short note, we review and comment on some examples where conversely, an effective behavior of non-abelian gauge theories in some particular limits are described by some type of extended objects like strings or branes. We constrain the discussion to a few examples sharing some similarities.
