Incidental Brane Defects
In the models of brane construction, the isometry of a compactified space might be broken by branes. In four-dimensional effective Lagrangian, the breaking of the isometry is seen as the spontaneous breaking of the corresponding effective symmetry. Then it seems natural to expect that there are various kinds of defects that will be implemented by the spontaneous symmetry breaking. These defects...
متن کاملFormation of cosmological brane defects
We study cosmological formation of D-term strings, axionic strings, domain walls and Q-balls in braneworld models of the Hanany-Witten type. For the Dterm strings, we show that the strings are the daughter branes extended between mother branes. We show that the domain walls can be produced by conventional cosmological phase transitions. In this case, the formation of the domain walls is induced...
متن کاملBrane necklaces and brane coils
We investigate D-term strings in angled inflation and show how they could be distinguished from conventional cosmic strings. In angled inflation, D-term strings are Dp−2 branes that are extended between Dp branes. The Dp−2 brane has a flat direction in compactified space, along which the endpoint of the Dp−2 brane can move freely on the Dp brane. Then naturally the position of the Dp−2 brane co...
متن کاملSolitonic d-5 Brane and Vortex Defects on the World-Sheet
We examine the behavior of the vortex defects on the world-sheet when a solitonic d5 brane is existing in the d-dimensional target space, and it is seen that the vortices of any charge should be dissociated to the free-gas phase when they approach to the brane. The meanings of this fact are addressed through the analysis of the renormalization group equations on the world sheet. e-mail: gouroku...
متن کاملDefects in Chern-Simons theory, gauged WZW models on the brane, and level-rank duality
We consider Hanany-Witten setups of 3and 5-branes in type IIB string theory that realize N = (1, 0), (2, 0) and (1, 1) gauged WZW models in 1 + 1 dimensions. The gauged WZW models arise as theories residing on the boundary of D3 branes ending on D5 branes. From the point of view of low energy dynamics the D5 branes play the role of half-BPS co-dimension-1 defects (domain walls) in 3d N = 1 or N...
