STREPTOCOCCAL ("SEPTIC") THROATS.

Generic wormhole throats

Wormholes and black holes have, apart from a few historical oddities, traditionally been treated a quite separate objects with relatively little overlap. The possibility of a connection arises in that wormholes, if they exist, might have profound influence on black holes, their event horizons, and their internal structure. For instance: (1) small wormhole-induced perturbations in the geometry c...

Curvatons in Warped Throats

We present a curvaton model from type IIB string theory compactified on a warped throat with approximate isometries. Considering an (anti-)D3-brane sitting at the throat tip as a prototype standard model brane, we show that the brane’s position in the isometry directions can play the role of curvatons. The basic picture is that the fluctuations of the (anti-)D3brane in the angular isometry dire...

Spinflation and Cycling Branes in Warped Throats

The implications of brane motion in angular directions of Calabi-Yau flux compactifications are discussed from the point of view of an observer living on the worldvolume of the brane and from the point of view of an observer living elsewhere in the three non-compact dimensions. The brane observer can experience cosmological bounces and cyclic behavior of the scale factor induced by centrifugal ...

Small Numbers From Tunnelling Between Brane Throats

Generic classes of string compactifications include “brane throats” emanating from the compact dimensions and separated by effective potential barriers raised by the background gravitational fields. The interaction of observers inside different throats occurs via tunnelling and is consequently weak. This provides a new mechanism for generating small numbers in Nature. We apply it to the hierarc...
