Dielectric Branes in Non-trivial Backgrounds
We present a procedure to evaluate the action for dielectric branes in non-trivial backgrounds. These backgrounds must be capable to be taken into a Kaluza-Klein form, with some non-zero wrapping factor. We derive the way this wrapping factor is gauged away. Examples of this are AdS5 × S and AdS3 × S × T , where we perform the construction of different stable systems, which stability relies in ...
متن کاملBranes in Special Holonomy Backgrounds
We study the flow from the theory of D2-branes in a G2 holonomy background to M2-branes in a Spin(7) holonomy background. We consider in detail the UV and IR regimes, and the effect of topology change of the background on the field theory. We conjecture a non-Abelian N = 1 mirror symmetry.
متن کاملD-Branes in Nongeometric Backgrounds
“T-fold” backgrounds are generically-nongeometric compactifications of string theory, described by T fibrations over a base N with transition functions in the perturbative T-duality group. We review Hull’s doubled torus formalism, which geometrizes these backgrounds, and use the formalism to constrain the D-brane spectrum (to leading order in gs and α ) on T fibrations over S with O(n, n;Z) mon...
متن کاملDielectric - Branes
We extend the usual world-volume action for a Dp-brane to the case of N coincident Dpbranes where the world-volume theory involves a U(N) gauge theory. The guiding principle in our construction is that the action should be consistent with the familiar rules of T-duality. The resulting action involves a variety of potential terms, i.e., nonderivative interactions, for the nonabelian scalar field...
متن کاملExotic branes and nongeometric backgrounds.
When string or M theory is compactified to lower dimensions, the U-duality symmetry predicts so-called exotic branes whose higher-dimensional origin cannot be explained by the standard string or M-theory branes. We argue that exotic branes can be understood in higher dimensions as nongeometric backgrounds or U folds, and that they are important for the physics of systems which originally contai...
