Supersymmetric Defect Expansion in CFT from AdS Supertubes

TL;DR

This paper demonstrates how adding electric charge and angular momentum causes a planar superconformal defect in AdS/CFT to expand into a higher-dimensional supersymmetric defect, modeled by supertubes in string theory.

Contribution

It introduces a novel mechanism linking defect expansion in CFT to supertube formation in string theory within the AdS/CFT framework.

Findings

Defect expansion corresponds to supertube formation in dual string theory.

Electric charge and angular momentum induce higher-dimensional defect geometries.

The process preserves supersymmetry during the expansion.

Abstract

The AdS/dCFT correspondence is used to show that a planar q-dimensional superconformal CFT defect expands, under the addition of electric charge and angular momentum, to a supersymmetric higher-dimensional defect of geometry R^q x C, where C is an arbitrary curve. The dual string theory process is the expansion of D-branes and fundamental strings into a supertube in an AdS background.
