TL;DR
The paper demonstrates how a IIA superstring with D0-brane charge can expand into a supersymmetric tubular D2-brane, stabilized by angular momentum from electromagnetic fields, serving as a worldvolume realization of the sigma-model Q-lump.
Contribution
It introduces the supertube as a new stable, supersymmetric D2-brane configuration supported by electromagnetic angular momentum in Minkowski space.
Findings
Superstring with D0 charge can form a stable supertube.
Supertube is a (1/4)-supersymmetric tubular D2-brane.
The configuration is a worldvolume realization of the sigma-model Q-lump.
Abstract
It is shown that a IIA superstring carrying D0-brane charge can be `blown-up', in a {\it Minkowski vacuum} background, to a (1/4)-supersymmetric tubular D2-brane, supported against collapse by the angular momentum generated by crossed electric and magnetic Born-Infeld fields. This `supertube' can be viewed as a worldvolume realization of the sigma-model Q-lump.
