چکیده
When string/M-theory is compactified to lower dimensions, the U -duality symmetry predicts socalled exotic branes whose higher dimensional origin cannot be explained by the standard string/Mtheory branes. We argue that exotic branes can be understood in higher dimensions as non-geometric backgrounds or U -folds, and that they are important for the physics of systems which originally contain no exotic charges, since the supertube effect generically produces such exotic charges. We discuss the implications of exotic backgrounds for black hole microstate (non-)geometries.

The double field theory monopole solution by Berman and Rudolph is shown to reproduce non-geometric backgrounds with non-vanishing Qand R-flux upon an appropriate choice of physical and dual coordinates. The obtained backgrounds depend non-trivially on dual coordinates and have only trivial monodromies. Upon smearing the solutions along the dual coordinates one reproduces the known 52 solution ...

We present an octonionic N = 1 superfield action that reproduces in components the action of Bagger and Lambert for M2 branes. By giving an expectation value to one of the scalars we obtain the maximally supersymmetric superfield action for D2 branes.

We investigate DBI inflation using N multiple branes and show how the configuration is equivalent to a single wrapped D5-brane with flux. We then show how 1/N corrections can be implemented, and we examine the sound speed and levels of non-Gaussianities in two distinct cases. For models with constant warping we find that the non-Gaussian amplitude is bounded from above (as a function of γ). For...
