Supertubes versus superconducting tubes
نویسنده
چکیده
In this paper we show the relationship between cylindrical D2-branes and cylindrical superconducting membranes described by a generic effective action at the bosonic level. In the first case the extended objects considered, arose as blown up type IIA superstrings to D2-branes, named supertubes. In the second one, the cosmological objects arose from some sort of field theories. The Dirac-Born-Infeld action describing supertubes is shown to be equivalent to the generic effective action describing superconducting membranes via a special transformation.

Non-supersymmetric black rings as thermally excited supertubes
We construct a seven-parameter family of supergravity solutions that describe non-supersymmetric black rings and black tubes with three charges, three dipoles and two angular momenta. The black rings have regular horizons and non-zero temperature. They are naturally interpreted as the supergravity descriptions of thermally excited configurations of supertubes, specifically of supertubes with tw...
متن کاملSupertubes connecting D4 branes
We find and explore a class of dyonic instanton solutions which can be identified as the supertubes connecting two D4 branes. They correspond to a single monopole string and a pair of monopole-antimonopole strings from the worldvolume view point of D4 branes. 1 Introduction Recently there has been a considerable study of the so called supertube solutions. Originally Mateos and Townsend construc...
متن کاملThree Charge Supertubes and Black Hole Hair
We construct finite size, supersymmetric, tubular D-brane configurations with three charges, two angular momenta and several brane dipole moments. In type IIA string theory these are tubular configurations with D0, D4 and F1 charge, as well as D2, D6 and NS5 dipole moments. These multi-charge generalizations of supertubes might have interesting consequences for the physics of the D1-D5-P black ...
متن کاملPhase Moduli Space of Supertubes
We study possible deformations of BPS supertubes keeping their conserved charges fixed. We show that there is no flat direction to closed supertubes of circular cross section with uniform electric and magnetic fields, and also to open planar supertubes. We also find that there are continuously infinite flat deformations to supertubes of general shape under certain conditions.
متن کاملBoundary States for Supertubes in Flat Spacetime and Gödel Universe
We construct boundary states for supertubes in the flat spacetime. Since the T-dual objects of supertubes are moving spiral D1-branes (D-helices), which we can obtain from the usual D1-branes via null deformation, we can construct the boundary states for these moving D-helices in the covariant formalism. Using these boundary states, we calculate the vacuum amplitude between two supertubes in th...
