Non-BPS D-brane Solutions in Six Dimensional Orbifolds
Starting with the non-BPS D0-brane solution of IIB/(−1)LI4 constructed recently by Eyras and Panda we construct via T-duality the non-BPS D2-brane and D1-brane solutions of IIB/(−1)LI4 and IIA/(−1)LI4 predicted by Sen. The D2-brane couples magnetically to the vector field of the NS5B-brane living in the twisted sector of the Type IIB orbifold, whereas the D1-brane couples (electrically and magn...
متن کاملBrane Cosmologies without Orbifolds
We study the dynamics of branes in configurations where 1) the brane is the edge of a single anti-de Sitter space and 2) the brane is the surface of a vacuum bubble in an asymptotically flat space-time. In both cases we find solutions that resemble the standard Robertson-Walker cosmologies although in the latter, the evolution is not controlled by matter on the brane, but by the five-dimensiona...
متن کاملBps M-brane Geometries
In the search for a classification of BPS backgrounds with flux, we look at geometries that arise when M-branes wrap supersymmetric cycles in Calabi-Yau manifolds. We find constraints on the differential forms in the back-reacted manifolds and discover that the calibration corresponding to the (background generating) M-brane is a co-closed form. Contribution to proceedings of the 12th Regional ...

متن کاملMetrics on D-brane Orbifolds
We calculate the metric on the D-brane vacuum moduli space for backgrounds of the form C 3 /Γ for cyclic groups Γ. In the simplest procedure — starting with a flat " seed " metric on the covering space — we find that the resulting D-brane metric is not Ricci-flat. We argue that this is likely to be true of the true 0-brane metric at weak string coupling.
