Field Theory Supertubes
Starting with intersecting M2-branes in M-theory, the IIA supertube can be found by S compactification followed by a boost to the speed of light in the 11th dimension. A similar procedure applied to DonaldsonUhlenbeck-Yau instantons on C, viewed as intersecting membranes of D = 7 supersymmetric Yang-Mills (SYM) theory, yields (for finite boost) a new set of 1/4 BPS equations for D = 6 SYM-Higgs...
متن کاملSupertubes in Field Theories
To a domain wall or string object, Noether charge and topological spatial objects can be attracted, forming a composite BPS (Bogomolny-Prasad-Sommerfield) object. We consider two field theories and derive a new BPS bound on composite linear solitons involving multiple charges. Among the BPS objects ‘supertubes’ appear when the wall or string tension is canceled by the bound energy, and could ta...
متن کاملRotating Supertubes
We study the rotating tubular D2-brane as a time dependent supersymmetric solution of type-IIA string theory. We show that the Poynting angular momentum of the supertube can be replaced by the mechanical angular momentum without disturbing the 8 supersymmetries. Unlike the non-rotating supertube, whose cross section can take an arbitrary shape, the rotating supertube admits only the circular cr...
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 کاملDynamics of supertubes
We find the evolution of arbitrary excitations on 2-charge supertubes, by mapping the supertube to a string carrying traveling waves. We argue that when the coupling is increased from zero the energy of excitation leaks off to infinity, and when the coupling is increased still further a new set of long lived excitations emerge. We relate the excitations at small and large couplings to excitatio...
