Supergravity supertubes

We find the asymptotic supergravity solution sourced by a supertube: a 1/4-supersymmetric D0-charged IIA superstring that has been blown up to a cylindrical D2-brane by angular momentum. It has no net D2-brane charge but does have a D2-brane dipole moment. It also has closed timelike curves in the d...

description We find the asymptotic supergravity solution sourced by a supertube: a 1/4-supersymmetric D0-charged IIA superstring that has been blown up to a cylindrical D2-brane by angular momentum. It has no net D2-brane charge but does have a D2-brane dipole moment. It also has closed timelike curves in the dipole region, which leads to a ghost-induced instability of D2-supertube probes. We comment on similarities to the enhancon and the heterotic dyonic instanton.

We comment on similarities to the enhancon and the heterotic dyonic instanton.We find the supergravity solution sourced by a supertube: a (1/4)-supersymmetric D0-charged IIA superstring that has been blown up to a cylindrical D2-brane by angular momentum. The supergravity solution captures all essential features of the supertube, including the D2-dipole moment and an upper bound on the angular momentum: violation of this bound implies the existence of closed timelike curves, with a consequent ghost-induced instability of supertube probes.hep-th/0106012DAMTP-2001-49DAMTP-2001-49CERN-TH-2001-159oai:cds.cern.ch:5030182001-06-01
