Abstract
We study the “Myers effect” for a bunch of D1-branes with type-IIB superstrings moving in one direction along the branes. We show that the “blown-up” configuration is a helical D1-brane, which is self-supported from collapse by the axial momentum flow. The tilting angle of the helix is determined by the number of D1-branes. The radius of the helix is stabilized to a certain value depending on the number of D1-branes and the momentum carried by type-IIB superstrings. This helix is actually a T-dual version of the supertube recently found as the “blown-up” configuration of a bunch of type-IIA superstrings carrying a D0-brane charge. It is shown that the helical D1 configuration preserves one-quarter of the supersymmetry of the type-IIB Minkowski vacuum.Keywords
