D0-branes in flux 5-brane backgrounds
The existence of supersymmetric D0-branes sitting at an arbitrary distance from a flux 5-brane is proven. The physical picture in type IIA is consistent with the Kaluza-Klein reduction origin of the flux 5-brane. An analysis of the fluctuations around these vacua is performed and the backreaction of the D0-branes is computed. Non-threshold D0-D2 bound states and similar stabilization mechanisms...
متن کاملFlux Backgrounds in 2D String Theory
We study RR flux backgrounds in two dimensional type 0 string theories. In particular, we study the relation between the 0A matrix model and the extremal black hole in two dimensions. Using T-duality we find a dual flux background in type 0B theory and propose its matrix model description. When the Fermi level μ is set to zero this system remains weakly coupled and exhibits a larger symmetry re...
متن کاملComments on D-branes in flux backgrounds
We construct supergravity solutions for D-branes in nontrivial flux backgrounds. We revisit the issue of charge quantization in this framework, and show that in these backgrounds, charge need not be quantized. We also show in a particular example that the semiclassical description of branes produces integral charges. e-mail address: [email protected]
متن کاملSupersymmetric D-branes on flux backgrounds
Several aspects concerning the physics of D-branes in Type II flux compactifications preserving minimal N = 1 supersymmetry in four dimensions are considered. It is shown how these vacua are completely characterized in terms of properly defined generalized calibrations for D-branes and the relation with Generalized Complex Geometry is discussed. General expressions for superpotentials and D-ter...
متن کاملOn general flux backgrounds with localized sources
We derive new consistency conditions for string compactifications with generic fluxes (RR, NSNS, geometrical) and localized sources (D-branes, NS-branes, KKmonopoles). The constraints are all related by string dualities and share a common origin in M-theory. We also find new sources of instabilities. We discuss the importance of these conditions for the consistency of the effective action and f...
